Thanks for that info. Have to fly on a particular date, part of an itinerary. Four couples and it’s the only flight that is non stop. We all want exit rows.Jetstar fluctuates between 9-12 months. I asked yesterday and officially they are still finalising a schedule for July 2022.
There isn't any logic to this (particular release date) so you'll just need to keep checking as they could load them all in one go or drip them month by month. Regardless is there any reason why you're keen to book ADL-CNS in July next year. A lot can happen between now and then so it would be wiser (in my opinion) to book closer to the date.
