Never heard of them in Ox, but I did some research.
Oh what a tangled web we weave.
After trolling through all sorts of links, I "think" they have sold their interests to the mob which controls NRMA Insurance. But I can't be sure. I also found some references to The National Australia Bank buying into the mix a little while ago.
It would appear though, that whatever operations they had in Australia are now locally owned and controlled, sort of like when ING got out of Canada and left their operation in local ownership.
Aviva's website doesn't link to any Australian site.
Anyone else over here got any more definitive info?
