You can definitely pay for your VOA with AUS$ currency. The amount will depend on the day, but generally around $26-27 lately. They don't take coins though, so you'll pay whatever is rounded up to the nearest note and get change in rupiah.
Sorry but I can't help with the other questions as I don't use money changers or boot makers. I'm sure someone else will have those answers for you.
