Tapp0,
there are a few cadetships offer in OZ, most seem more attractive on the surface than they really are as they (can) lock you in to a pretty poor salary for quite some time afterwards.
The one cadetship that is probablly worth the most is the Qantas one, as they have changed it to being fully funded (I believe) as opposed to the 120k it used to be.
All the other cadetship still require you to cough up money, so nothing is free.
