In other news, it’s all happening in Victoria:

• Peter Costello’s surprise announcement that he will not contest the next election has raised the flag on another epic Victorian Liberal preselection stoush in his Melbourne seat of Higgins, which housed successive Liberal prime ministers in Harold Holt and John Gorton. Furthermore, Costello has raised the possibility of an early departure and a by-election, “if it’s in the party’s interest”. Immediately prior to Costello’s announcement, Institute of Public Affairs executive director John Roskam signalled his intention to run if Costello stood aside, after earlier testing the waters in Kooyong (see below). However, Peter van Onselen in The Australian reports that Costello has resolved to oppose Roskam due to equivocal comments he made to David Penberthy of The Punch about Costello’s future value in politics. Van Onselen further reports widespread displeasure at this and other remarks seen to be in breach of Liberal rules that preselection aspirations are not to be discussed with the media. Costello reportedly wishes for the seat to go to a former staffer, Kelly O’Dwyer. It had earlier been reported that O’Dwyer might depose incumbent Ted Baillieu loyalist Andrew McIntosh in the state seat of Kew. The other big name in the Higgins mix is Mal Brough, who has moved to Melbourne and is said to be hopeful of a return to politics that doesn’t involve further dirtying his hands in the morass of the Queensland Liberal National Party. However, Phillip Coorey of the Sydney Morning Herald reports party sources say he has “no chance”. Also mentioned are former state party director Julian Sheezel, who was said to be backed by Costello but opposed by Michael Kroger when talk of Costello’s departure was in the air after the election, Jason Aldworth, a former banking colleague of Michael Kroger and more recently a consultant for Crosby Textor; and, intriguingly, Tom Elliott, hedge fund manager and son of John, who memorably sought to depose Roger Shipton as member for this very seat in pursuit of his prime ministerial ambitions.

• Merchant banker Josh Frydenberg has won the hotly contested preselection to succeed Petro Georgiou as the Liberal candidate for Kooyong. Andrew Landeryou at VexNews reports that Frydenberg won the second round ballot over industrial relations lawyer John Pesutto by 283 votes to 239 after all other contenders were excluded in the first round. The result is a defeat for Ted Baillieu, whose power base had pursued various stratagems designed to thwart Frydenberg, the preferred candidate of the rival Kroger faction.

• The ALP national executive’s role in Victorian state preselections has been further expanded following John Brumby’s decision to refer to the body all state upper house preselections for next year’s election. Labor insiders quoted by David Rood of The Age relate that the decision will “all but end” the career of Theo Theophanous, who faces a vigorously contested rape charge and was recently among those named adversely in the state Ombudsman’s report into Brimbank City Council. This week the national executive acted as expected in relation to a number of lower house preselections referred to it in the wake of the latter imbroglio, selecting former Trades Hall Council deputy secretary (and wife of New South Wales Senator Steve Hutchins) Natalie Sykes-Hutchins to replace George Seitz in Keilor and confirming incumbents Telmo Languiller, Rob Hulls, Marsha Thomson and Marlene Kairouz in Derrimut, Niddrie, Footscray and Kororoit. It has also been confirmed that Victorian Planning Minister Justin Madden will seek to move to the lower house by nominating for preselection in Essendon, to be vacated by the retiring Judy Maddigan. In his absence, the national executive has chosen incumbents Martin Pakula, Khalil Eideh and Bob Smith to head the ticket in Western Metropolitan (Smith currently represents South-Eastern Metropolitan).

• Helen Shardey, Victorian Shadow Health Minister and member for Caulfield, has indicated she will stand down at the next election. It had been reported she faced a preselection challenge from David Southwick, previously unsuccessful in the federal seat of Melbourne Ports in 2004 and for the state upper house Southern Metropolitan in 2006.

• Andrew Landeryou at VexNews reports that former Liberal MP Phil Barresi, whom he describes as a “factionally unenthusiastic Krogerite”, has been given the green light to attempt to recover the seat of Deakin which he held from 1996 until his defeat in 2007. Barresi reportedly won on the first round over eccentric perennial Ken Aldred, who was dumped in favour of Barresi in 1996 after peddling weird conspiracy theories, and one Deanne Rhyll. Perhaps Barresi is encouraged by the precedent of 1984, when the Liberals unexpectedly recovered the seat (with some help from a redistribution) after losing it when the Hawke government was elected in 1983.

Elsewhere:

• Glenn Milne in The Australian reports on the Labor succession in the federal seat of Macquarie, which will be vacated at the next election by Bob Debus. As Milne tells it, Debus or his supporters put it about that his recent decision to withdraw from the ministry and bow out at the next election, which helped the Prime Minister no end as he sought to construct a new cabinet in the wake of Joel Fitzgibbon’s resignation, was conditional upon Debus being given the right to anoint his own successor. This was hotly disputed by Right powerbrokers who are bitterly opposed to Debus’s objective of freezing out industrial barrister Adam Searle, a Left faction colleague but personal rival.

• Two new goodies from Antony Green. An extensive paper for the New South Wales Parliamentary Library provides all manner of detail on the state’s Legislative Council election in 2007, while an accompanying blog post scrutinises the performance of the optional preferential above-the-line voting system introduced after the 1999 election produced a tablecloth-sized ballot paper and elected candidates from groupings that would be flattered by the “micro-party” designation. He further discusses the potential for such a system to resolve the issues which saw Steve Fielding elected to the Senate in 2004. For the more casual election enthusiast, a new 2010federal election calculator allows you set the two-party result to taste to find out the seat outcome in the event of a uniform swing. It turns out a 50-50 result would give the Coalition exactly half the seats and presumably allow it to govern with support of the three independents. Labor loses its majority at 50.8 per cent.

• Queensland independent MP Peter Wellington has introduced a private member’s bill providing for fixed three-year terms, with an escape clause if a new government cannot be formed in the wake of no-confidence motion and a provision allowing for a five-week postponement if there is a clash with a federal election or a “widespread natural disaster”. The major parties both support fixed four-year terms, which unlike Wellington’s proposal would require a referendum. Negotiations for such a referendum broke down last year when then Opposition Leader Lawrence Springborg insisted on further unrelated reforms, but his successor John-Paul Langbroek has foreshadowed a more “flexible” approach in future discussions with the government.

• Christian Kerr of The Australian evaluates the Australian political blogosphere.

UPDATE: Thanks to Rebecca in comments for bringing my attention to the fact that Allison Ritchie, Labor member for the Tasmanian Legislative Council district of Pembroke, yesterday announced she would quit parliament after enduring a storm of controversy over her appointment of family members on her staff. This will presumably result in a by-election shortly in Pembroke, where Ritchie defeated an independent incumbent in 2001 and won re-election in 2007. The Electoral Act allows the government enormous latitude on the timing of such a by-election, so I’ll hold off on giving it its own post until its intentions become clearer. Ritchie claims to have been the victim of a plot from within her own party, which presumably explains why she has decided to go now rather than wait for the more convenient juncture of early next year, when a by-election could be held with the state election in March or the annual periodical upper house elections in May.

• Phillip Coorey of the Sydney Morning Herald reports that “branches in the Sutherland Shire seat of Cook are being furiously stacked in what moderates say is an attempt to ward off a potential challenge by the far right to the sitting Liberal member, Scott Morrison”. However, Right sources deny any such plan and instead argue the stacking is being conducted in pursuit of the moderates’ own designs against Morrison. Central to the ongoing dispute is Michael Towke, whose preselection win upon the retirement of Bruce Baird at the 2007 election was overturned by the party’s state executive following reports of branch-stacking activities and extravagant claims made in his CV. The seat instead went to the well-connected but factionally unaligned Morrison, who went on to suffer humiliation at the hands of the local Right-controlled branches which refused his membership application a few months after he entered parliament. Talk of ongoing Right designs on the seat received further impetus when Towke secured the position of Cook electoral council secretary. Coorey reports there are rumours afoot that the Right will seek to have state upper house MP Marie Ficarra depose Morrison, making her own position available to Towke – although this was “laughed off” by a “senior Right source”.

• Phillip Coorey of the Sydney Morning Herald reports the Labor national executive has given Kevin Rudd and the five-member national executive committee (Anthony Albanese, Mark Arbib, Mark Butler, Bill Shorten and Bill Ludwig) extensive powers over federal preselections. State branches will not be able to start preselection processes without the permission of the committee, which will further have the power to replace sitting members – significantly including Belinda Neal, the troubled member for Robertson.

• Andrew Landeryou at VexNews reports that Victorian Liberal leader Ted Baillieu, director Tony Nutt and president David Kemp have moved without reference to the party’s administration committee to truncate the preselection process for next year’s state election from eight weeks to four. Baillieu opponents say this is a move to shore up the position of his backers Andrew McIntosh (Kew), Helen Shardey (Caulfield) and Kim Wells (Scoresby). Landeryou also relates rumours about the possible departure of Liberal deputy leader Louise Asher, the member for Brighton.

• Liberal Party members in the Victorian federal seat of Corangamite, which the party lost in 2007, will today vote for a candidate at the next election. The front-runners are said to be Sarah Henderson, former 7:30 Report host and daughter of the late former Geelong state MP Ann Henderson, and Rod Nockles, internet security expert and former Howard government adviser. Others who have been mentioned at various stages include Victorian Farmers Federation president Simon Ramsay, more recently mentioned in relation to Wannon; former Kennett government minister Ian Smith; Graham Harris, head of the Corangamite electorate council; Simon Price, unsuccessful Colac Otway Shire Council candidate and former electorate officer to Stewart McArthur; and Michael King, owner of Kings Australia funeral services. (UPDATE: Sarah Henderson wins. See Andrew Landeryou and his comments thread for much confusion over who backed whom.)

• There was renewed talk this week that Victorian Planning Minister Justin Madden could be moving to the lower house. It was initially suggested he would take the seat of Keilor, expected to be forcibly vacated by controversial Right faction numbers man George Seitz. However, Madden has ruled this out, saying it would not be a good look for him to take the seat given the role of his staffer Hakki Suleyman in the Brimbank City Council controversies which are set to initiate Seitz’s departure. Madden said he did not want, but would not rule out, taking the retiring Judy Maddigan’s seat of Essendon. Prior to the 2006 election, it was planned that Madden would be accommodated in Bundoora due to the reduction in the size of the Legislative Council, but a rearrangement following Mary Delahunty’s departure from Northcote saw him stay put.

• The New South Wales Nationals’ annual state conference has resolved to proceed with an exciting plan in which a candidate in a yet-to-be-determined state electorate will be chosen by an American-style open primary, in which all voters in the electorate will be able to participate.

• On Monday, Galaxy published a survey of 1004 respondents showing federal Labor with a two-party lead of 55-45. The primary vote figures of 43 per cent for Labor and 40 per cent for the Coalition are similar to those from the 2007 election, suggesting the two-party result flatters Labor a little. Furthermore, 17 per cent nominate themselves less likely to vote Labor if an early election is called against 12 per cent more likely. Kevin Rudd was rated “arrogant” by 31 per cent against 47 per cent for Malcolm Turnbull, while their respective ratings for being “out of touch with ordinary Australians” were 29 per cent and 48 per cent. However, Rudd performed worse than Turnbull on the innovative measure of “someone who can turn nasty if he doesn’t get his own way”, scoring 43 per cent to Turnbull’s 31 per cent. Peter Brent at Mumble has tables.

• Tasmanian Electrical Trades Union secretary Kevin Harkins apparently plans to proceed with his bid for Senate preselection, despite having been told by Kevin Rudd his chances were “Buckley’s and none”. Harkins was endorsed as candidate for Franklin ahead of the 2007 election, but was compelled to step aside four months beforehand after his colourful activities as a union leader emerged as a political liability. It was reported at the time that the pill had been sugared with offers of “an elevated union position, increased salary and a future Senate seat”. Harkins is the favoured candidate of the Left faction for one of the two safe Senate seats, with incumbent Kerry O’Brien set to be dropped to loseable third. The Hobart Mercury reports that the Left’s position is now likely to go to Australian Manufacturing Workers Union secretary Anne Urquhart, who is seen as acceptable to the Right. The Right’s position at the top of the ticket will remain with the low-profile Helen Polley.

• Michael Owen of The Australian reports on tension in the South Australian Liberal camp over Senate preselection, with Right faction colossus Nick Minchin “warning off” moderate state president Sean Edwards. Minchin says Edwards had undertaken not to seek preselection when he ran for the presidency in 2007 so he could focus on next year’s state election. A “party source” says the Right has secured the postponement of preselection until April next year so a newly elected state council can provide them with a more favourable result, potentially leaving the party unprepared for an early election. The Right’s chief concern is to secure a seat for David Fawcett, defeated in Wakefield at the 2007 election, at Edwards’ expense. Alan Ferguson, who is associated with the Right faction and the conservative Lyons Forum, is “expected to retire” rather than seek another term.

• After holding the seat since Malcolm Fraser’s departure after his 1983 election defeat, David Hawker has announced he will retire as member for Wannon at the next election. Andrew Landeryou at VexNews has a comprehensive form guide of potential preselection aspirants, including “complicated Costello loyalist” Georgie Crozier; Victorian Farmers Federation president Simon Ramsay, said to be facing a losing battle against former Howard government adviser Rod Nockles in his bid for the less appealing prospect of Corangamite; Institute of Public Affairs agriculture policy expert Louise Staley, who challenged Kevin Andrews for preselection in Menzies ahead of the 2001 election; former police sergeant and anti-corruption crusader Simon Illingworth; “farmer, vet and former local councillor” Katrina Rainsford; and the similarly credentialled Matt Makin.

• Left faction Victorian state MP Carlo Carli has announced he will not re-contest Brunswick at the next election, perhaps boosting the Greens’ vague chances of snaring the seat. Andrew Landeryou at VexNews once again offers a goldmine of detail on preselection contenders, describing the seat as an “area of conflict” between the competing Left faction camps associated with federal Bruce MP Alan Griffin and Senator Kim Carr. Griffin faction aspirants include former state secretary Eric Locke and Moreland councillor Alice Pryor, while the only identified contender from the Carr camp is 23-year-old Enver Erdogan, a staffer to House of Representatives Speaker Harry Jenkins. Apparently straddling the two camps is Danny Michel, an adviser to Public Transport Minister Lynne Kosky. Moreland’s Right faction mayor Lambros Tapinos is also named as a “wild card”.

• Yet more from the House of Landeryou: preselection challenges apparently loom against two senior Victorian state Liberals, Shadow Police Minister Andrew McIntosh in Kew and Shadow Health Minister Helen Shardey in Caulfield. The story in Kew goes that a Josh Frydenberg federal preselection victory in Kooyong would unleash “irresistible pressure” for McIntosh to be dumped in favour of “Costello loyalist” Kelly O’Dwyer. In Caulfield, “local power-broker” Frank Greenstein proposes that Shardey make way for David Southwick, who previously contested the federal seat of Melbourne Ports in 2004 and was narrowly pipped by short-lived Labor member Evan Thornley for an upper house seat in Southern Metropolitan in 2006. Ted Baillieu is apparently very keen that none of this transpire, as both McIntosh and Shardey are loyal to him.

• The Australian reports the June 30 deadline for Victorian Liberal federal preselection nominations has ratcheted up speculation about Peter Costello’s future plans, with the overwhelming expectation he will seek another term in Higgins. Kevin Andrews is expected to face a challenge in Menzies, but is “believed to have the numbers”.

• UMR Research has published one of its occasional polls on attitudes to republicanism, showing little change since November. Support is up one point to 51 per cent, opposition is up two to 30 per cent. Support for direct election of the president is up a point to 81 per cent, with opposition stable on 12 per cent. Fifty-three per cent support a referendum during the next term of parliament.
