Hi Carl,
I own a 1969 Rover 2000 automatic in South Australia. I keep it in Adelaide. Most of the time I reside in the United States though. You might want to join the Rover Club of South Australia. They are a good group, and I know of at least on member who lives in the mid North.
Post some photos! Show people how little cars rust in South Australia. You do not learn about rust repairs in South Australia, as very few cars rust.
James.
