Hey ed,
One of the best storage things I've found is applying Renaissance Wax to the blades, and I also treat the scales too. Great stuff and used by the British Museum. Here's a link to a source (don't think it'll help you since it's in California) but you can read about it and then maybe source it down under. Oz may have a clue to finding it.
I even treat my regular rotation of razors with it too. Helps keeps soap, etc. from adhering to the blade.
