I am heading up to Mt Barker to my sister's place today with the scope. I have tried this a few time this year but each time the clouds rolled in.
For the local astronomy club look here
http://www.assa.org.au/ I guess I should join. I am hoping to get to their next public night at Stockport.
I will have to check out Jupiter creek, that sounds interesting. Most public parks that I find locally have floodlights in the carpark, or are too exposed to street lighting.
