Jetstar is bringing 5 of its 787-8 Dreamliners out of storage for domestic flights from June. It looks like these are to be used on the Sydney/Melbourne to Cairns/Gold Coast routes, and since Jetstar doesn't sell business class tickets on these routes, you could choose your seat from one of the 21 up front in the J cabin!
With the govt-subsidized half-price flights - still available on these routes, it means it's possible to score a flight from $62 one way in a Business class seat by paying $18 to choose your seat, and if you upgrade to the Max Bundle - half off as well - you can get a flight from $85, including 20 QF status credits, 1200 points, seat choice, an inflight meal AND 30kg luggage included!
So which flights?

On the Jetstar website, you'll want to double check that the plane is indeed a 787 Dreamliner. And there's also the risk that they change the plane in the days leading up to it, which would leave you with still the ability to choose a seat, but, it could be on a regular A320/1 instead.
If you're a Qantas Gold, Platinum or Platinum One frequent flyer, or a Qantas Club member, you are entitled to access Qantas Club lounges before your Jetstar flight on any fare type, where a lounge is available / open.
