The federal government funds a scheme that provides school chaplains to primary and secondary schools. This was started under the regime of John Howard, but continues under Kevin Rudd. The Rudd government has promised to "provide an additional $42.8 million to extend the NSCP for all participating schools until December 2011."
However, you can have your say about it. There is currently a public consultation process which you can read about here. The process runs in two stages, with a first call for submissions open until the end of May. A discussion document will then be produced, and a second process opened in June. Submissions can be sent to: email@example.com.
Frankly, not that much notice gets taken of individual submissions from members of the public (as opposed to lobby groups or supposed experts). However, the cumulative effect of many submissions going one way or the other does matter. Personally, I think that the government has no business funding religious views in public schools, even within the constraints described on the site. There's even some doubt as to whether this is constitutional in Australia (but that's a long story in itself). Even if you disagree with me, go ahead and let 'em know what you think.
