If you change all your money before leaving home, you will lose money on a bad rate. I've seen the airport money exchange offering around 20% less than what you'll get in Bali. That's a lot to lose on your entire holiday's spending money.
I wouldn't change any money at all in Sydney - definitely no more than $50 (more than enough for both of you - even $20 would suffice) if you feel you must. There's money changers at the arrivals that will give you a better rate than Sydney. And outside the airport, you'll do better again.
You can pay your VOA in Australian dollars, so no need for rupiah there.
