Croucher had widely been tipped to take on the role, with Attorney-General George Brandis confirming the appointment via a statement.
She will start her seven-year term on the 30th July.
Croucher is currently president of the Australian Law Reform Commission, and had a long and distinguished academic career prior to joining the ALRC, including as Dean of Law at Macquarie from 1999 until 2007. Last week she released ALRC’s final report into the abuse of older Australians by carers.
Croucher has previously announced her support for reforming section 18C of the Racial Discrimination Act.
Brandis described Croucher as “pragmatic, constructive” and with an “analytical approach to law reform.”
