If money is not an option you can't go past a ju-ju-be. you can order from their American website or from mamasandmunchkins (a site recommended to me who sell to australia and have good postage rates). I am getting one of these...they are teflon coated, machine washable (big Plus!) and have metal hardware for durability........and they have heaps of oh so funky prints!!!

If you are really really rich you may want to have a browse of petunia picklebottom......bit pricey but lush fabrics!

Just a couple of alternatives to the OI OI which is probably the best of the aussie labels...either OIOI or ISOKI if you want an aussie bag.
