Various conversations with various people. The Townsville refueller is best.
I'm all seriousness, if a former cadet on placement with Qlink was starting in 4 weeks we'd know about it here on PPRUNE about 15 minutes (perhaps less) after they got the phone call.
I simply asked someone who should know if there were trainees starting in April and the response was 'no, next FY'. Maybe they're right. Maybe they're not. Maybe it won't be the start of the FY and it'll be a bit later. That's the info I have though.
The numbers thrown around at recent meetings indicate still circa 150 on LWOP to phase back in over the next couple of years. Suspect not all of them will return but that may not be many.
