Congratulations!
I did the same last August. my future residence is in Seymour, VIC (quite dark, compared to Mt Waverley !! )
It is rented at the moment.. when retirement time comes ( hopefully in a 2-3 years but one never knows what will happen and when.. ) we are going to live there.
The plans for 2.3 metres Sirius dome are already on the table
There will be a space in a shed for workshop as well ( with mini lathe and milling machine).
