what territory is melbourne in

Melbourne isn’t in a territory at all; it’s in the state of Victoria, and it’s the state capital to boot.

Australia’s territories are mainly the Australian Capital Territory and the Northern Territory; Melbourne belongs to neither, unless your map was printed upside down after a long lunch.

If you need the shorthand, it’s VIC, not ACT and definitely not NT.

So there you go: city of laneway coffee and fickle weather, firmly a Victorian.
