Hi Oscar,
They would take new grads I think. The written exam and practical were reasonable hard and expensive. You'll spend about 2000 pounds before you've done. It may be easier to apply to New Zealand (no exam required) and then Australia and New Zealand have an agrerement.
I did the written exam in London, March 05.
Speak to some recruitment agencies in New Zealand about the whole thing. I think I found out about the on 'seek.com.nz'.
