Australia's Statute of Westminster Adoption Act 1942 receives royal assent.

The Statute of Westminster Adoption Act 1942 is an act of the Australian Parliament that formally adopted sections 2–6 of the Statute of Westminster 1931, an Act of the Parliament of the United Kingdom enabling the total legislative independence of the various self-governing Dominions of the British Empire. With its enactment, Westminster relinquished nearly all of its authority to legislate for the Dominions, effectively making them de jure sovereign nations.
