Peter,
You bring up good points and I have no knowledge of how things work in Australia. I was thinking about the RRS Versa 4 series also but when I checked, there is still no pricing and availability posted at this point.
As I've mentioned previously in other posts, our retirement plan B involves a move to Indonesia. I'll have to factor in repair options for my various pieces of equipment. I was surprised to find out that Canon's battery chargers work anywhere in the world without anything more than a plug adapter.
