For "hiring as a dev", $40/hr seems in the right ballpark.
For freelance work, I've paid well over $100/hr to people with similar age/experience based on nothing more than portfolios similar to his and a plausible sounding phone-screen.
I've contracted students for work, and while I'm more likely to propose payment terms based on estimated hours with payment on milestone delivery rather than just hourly rates, I'll still assume a similar overall "hourly rate".
Not in Australia. Minimum wage is ~$20/hour +/- $2 (That's about $22US). But you know, income is more equal here, so we don't have the highs. I think $60-$80/hour considering it is freelance.
