A few guys were doing bridging courses by distance through Charles Darwin univeristy in Darwin back in the day.
I believe their English course is qantas approved. Their maths used to be, but not anymore. You can do a qantas approved maths course via distance through quite a few service providers.
If you jump on the qantas mainline recruitment page for pilots there is all the info you need there.
Jetstar, virgin, tiger, alliance, and network don't require it.
QantasLink and Qantas mainline do.
