I'm in Tasmania, been into urban exploration since 2006.
Urban explored in Hobart and Melbourne.
Popular site(s) you would recognise, is "The Maze" that I have visited in Melbourne (several times in the summer when it was stinking hot and air-conditioned comfort down there with a 6pack of beer with mates) I was in another drain in Melbourne and I can't remember the name of the suburb bugger!
Also visited several drains in Hobart, one drain I went down I crawled a chamber for a rough 20 meters and found there would be no standing ground to walk properly!
Great getting muddy down there, abandoned buildings are a goodie, not many in Tasmania.
