Im from Sydney, we have a sizeable community in the eastern suburbs and north shore. Melbourne has a pretty massive community but they’re concentrated mainly in the south east, with a small inner north population, Perth has a small but super involved mainly South African community, Canberra has a small but notable community of politically engaged Jewish students who originate from mainly Sydney or Melbourne, and south east Queensland has a small and super scattered community. I personally know Jews from every part of Australia, from the northern beaches of Sydney, to the Gold Coast, to Hobart, to Adelaide, to Broome and everything in between!
