Jetstar is having a huge sale across the whole of Australia. Lots of seats available. The travel dates vary by route but are generally late Feb to late March or April - June/21. Jetstar is a budget airline so bags + meals are extra. Avalon Airport (AVV) in Melbourne is labelled separately to Melbourne Tullamarine Airport (MEL) as it is usually cheaper, but not useful for most travellers.
Travel restrictions are making air travel a lottery at the moment. Jetstar have added something called "FareCredit" which is an extra fee so that you can automatically get credit for flights if you want to cancel them.

As far as I am aware, this replaces the "Fly Flexible" campaign which was for flights up to Nov/2020 and allowed you to change your flights for free.
