Third-Party
Topcashback has 8.5% cashback on the Amazon categories "Kitchen & Dining" & "Tools" categories at Amazon. Filter by the items that ship to Australia to see what you can buy.
In the kitchen category they have a wide array of cookware (if you buy single pots/pans shipping is ok) & kitchen utensils.
In the tools category you could buy some rechargeable power tools (e.g combine with the dremel holiday promotions), tool accessories or soldering supplies (I bought some flux and wire strippers).
I also bought a Dremel 8220 the other day - which charges fine with a stepdown converter.
There is 8.5% on "Patio, Lawn & Garden" too - but this probably isn't quite as interesting.
Ends "today" - but that is US time, so probably later tonight.
Wow, tough crowd. Anyway I'll be buying a bunch of stuff tonight using this - really don't understand why people go bananas over an extra 0.05% cashback on ebay and ignore 8.5% on Amazon.
