An argument in favour of secession is based on the assumption that a federal government in Canberra will favour the business and popular interests of the larger population centres. A common complaint is that Western Australia is a forgotten or Cinderella State, which contributes more to federal funds than it gets back, and is discriminated against by the more populous states. The Constitution of Australia, however, describes the union as "one indissoluble Federal Commonwealth" and makes no provision for states to secede from the union.
