Jetstar pilots don't fly Qantas branded aircraft, so unless they start flying flights with the primary call sign as Qantas xxx, then there would be no effect.
Kremin, I don't think you are correct. I think you will find that any flight which is part of the Qantas Group with a Qantas codeshare flight number on it gets caught the same way Jetconnect and EFA do. The Atlas 747 freighters get caught as they use Qantas call signs as do Cobham B717's for Qantas link. Nearly all Jetstar flights have a Qantas codeshare on them. It can be either.
You need your AIPA insider to give explain to you the definition of a Qantas flight. I've had it explained to me. Better still get a copy and read it yourself.
