Jetstar has launched their Easter Sale for 2017. Plenty of great fares starting from just $29 (Avalon <-> Hobart). There's far too many to list them all, but you can easily check by selecting 'departing' and entering your city of preference. Travel dates also vary quite a bit, but there's cheap fares right through to December. Safe travels :)
Checked baggage is not included but may be added for a fee. Prices based on deselection of optional extras and on payment by POLi, Jetstar voucher, Jetstar Gift Card, Jetstar MasterCard or Jetstar Platinum MasterCard for bookings through jetstar.com
