Jetstar have had a few good opening specials.
Please ensure you read the fine print in detail - pay for all meals, pay for *all* drinks (apart from the one small bottle of water you get at your seat on boarding), pay for amenities, observe strict check-in times (they're ruthless on that) etc. They're fine to fly with, but their LCC model they use for Domestic Oz has basically been transplanted over onto their International routes with some slight tweaking. It's okay to take your own food/drinks on board, but they won't supply cups, cutlery, napkins, crockery etc. The prices are not all that friendly - $3 for a coffee, $2 for a coke, $15 for a meal etc.

A major full service carrier they are not, but as you alluded to, for the price, who cares !
