Well actually the labor government in Australia is currently reviewing the migrant intake policies mentioned in the main article ... http://www.iht.com/articles/2009/01/18/business/ozjobs.2-410... But it looks like we're going to keep up the high intake for the most part. We're certainly not losing any from what I've observed.
As an aside I have to say I haven't seen much of anti-immigration sentiment here even with the economic downturn. Sure, there's been a fair bit of talk against moving jobs overseas, but barley a whisper with regards to immigration.
