I am not sure if these are available "down under" but Ziplock makes a vaccum ziplock bag. You seal the bag, and using the hand pump that you get in the starter kit, suck all the air out.
I use these for my feeder rats - keeps them from getting freezer burn = longer lasting=less money spent
But for me, since I only have Skeeter - gives him the variety - but I don't waste food (especially the squashes - the grocery store won't let me cut one in 1/4).
