The new Australian government is remarkably conservative for a nominally Leftist government so it is likely that its Leftist moves will be more token than significant. And the resolve of Prime-minister-elect Kevin Rudd to sign the Kyoto treaty is a good example of such tokenism. Australia's emissions of carbon dioxide are already in line with what most of Europe has achieved so the signing will make little difference.
It should also be noted that Rudd will have to get the treaty through the Senate and, in a quirk of Australian politics, he is unlikely to be able to do that until July, 2008. Senate membership does not change until then and the present Senate is conservative-dominated. So Rudd's talk of "immediate" action is just the usual political flim-flam.
I doubt that the Iraq withdrawal will happen soon either. Time will tell.
