The Statute of Westminster Adoption Act 1942 is an Act of the Australian Parliament that formally adopted the Statute of Westminster 1931, an Act of the British Imperial Parliament enabling the legislative independence of the various self-governing Dominions of the British Empire. The Statute of Westminster allowed the Dominion parliaments and governments to act independently of the British Parliament and Government.
The Act is more important for its symbolic value than for the legal effect of its provisions. While Australia's growing independence from the United Kingdom was well accepted, the adoption of the Statute of Westminster formally demonstrated Australia's independence to the world. It also symbolised the shift in Australia's foreign policy from a focus on the United Kingdom to the United States.
