"Australia’s Jewish population was estimated to number 112,000 people in 2011 and constituted 0.5% of the national population. A more recent estimate in 2016 revises the figure to 113,000.7 The community is principally bimodal with 87% of the population living in Victoria or New South Wales. Within Victoria, 98% of Jews live in Melbourne, and in NSW 95% of Jews live in Sydney."
