Hi Stephan.
I also live in the Adelaide Hills. Moved to a dark sky site in April and haven't had my scope out yet (8inch SCT on a yet to be used HEQ5Pro). It's really been throwing the rain down this winter. I think we've had nearly 500mm here since we moved in - in an area that has 550 - 650mm annually.
Enjoy the dark sky.
Regards
Stewart
