Being the most populous city in Australia, and one of the most distinct and well-known cities in the world, Sydney shouldn’t come as a surprise to be the most expensive city to live in Australia. Mercantilism has been the name-of-the-game in Sydney, evidenced by the number of multinational corporations that have their headquarters located here. Regional Development Australia’s Economic Profile mentioned that 48% of Australia’s top 500 corporations have their headquarters here. With a lot of multinational corporations come corporate employees with a lot of money – making Sydney the most expensive place to live in Australia.
