Gligg, if you look very carefully at the word used, you will able to decode QF's intent:
Qantas Group Pilot Academy In partnership with FTA . Everything you need to understand is on that page, you just need to consider the inferences.
Group is the operative word. Within the group, the biggest shortage is on the DASH-8's. Graduates from the Academy could reasonably expect to go to DASH land to gain sufficient experience to go into the RHS of a B737 or an A32x. That is the current pipeline, and I would expect it to continue fore the foreseeable future.
Externals will still be important to moderate the flow out of the regionals, particularly if you have experience to enable direct to the 737 RHS . QF have to throw a bone to the regionals through mainline opportunities in a reasonable time so they don't leave the group once they have experience, but they have to balance the attrition rate to be able to keep the aircraft flying, which I believe is quite a challenge.
