In 1997 to 1998, Croucher was the Acting Dean of the Sydney Law School and then the Deputy Chair of the University of Sydney Academic Board in 1999. She then moved to Macquarie University as the Dean of the Macquarie Law School from 1999 to 2007. From 2002 to 2003, Croucher was the Chair of the Council of Australian Law Deans and the Vice-President of the International Academy of Estate and Trust Law from 2000 to 2005. Croucher's academic expertise as a lecturer and researcher is in the fields of equity, trusts, property, inheritance and legal history. She has written or edited nine books, including Succession: Families, Property and Death, Families and Estates: A Comparative Study, and Law and Religion – God, the State and the Common Law. She has also authored over 100 publications including book chapters, encyclopedia entries, journal articles, casenotes and conference papers.
Croucher was appointed a full-time Commissioner of the Australian Law Reform Commission by the Howard Government in 2007 and was made President in 2009. Croucher was reappointed President in 2014 and subsequently in 2015 for a further three-year term. Croucher was the Commissioner-in-charge of nine significant law reform inquiries including into Client Legal Privilege, Secrecy Laws, Family Violence, Discovery, Age Barriers, Disability Laws, the Freedoms Inquiry, and the Elder Abuse Inquiry.
On 20 June 2017, Attorney-General George Brandis announced that Croucher would be appointed President of the Australian Human Rights Commission in place of Gillian Triggs. Her seven-year term began on 30 July 2017. In March 2018, Croucher wrote a report recommending that compensation be awarded to a man because he was refused employment by banking and insurance company Suncorp Group. The man had previously been convicted and sentenced to 12 months’ jail in 2008 for accessing child pornography via a “carriage service” and for possession of child pornography, and did not disclose the convictions to the company in his initial online application. Croucher defended her report on the basis that, under Australian law, people should not be discriminated against in employment because of their criminal record, if the criminal record did not prevent them from carrying out the "inherent requirements" of the job.
