The Solicitor-General is the second law officer of the Commonwealth of Australia.

The functions of the Solicitor-General under s 12 of the Law Officer's Act 1964 (Cth) are to act as counsel for the Commonwealth and its emanations, to furnish opinions on questions of law referred to him by the Attorney-General and to perform such other functions ordinarily performed by counsel as the Attorney requests.

The Solicitor-General appears in most matters in the High Court of Australia involving the Commonwealth and its emanations and in select matters of importance in the intermediate appellate courts of Australia. The Solicitor-General has a wide practice, appearing in matters involving constitutional law, extradition, migration, native title, trade practices, taxation, corporations, customs, international arbitration and criminal law.

The Solicitor-General will ordinarily appear as one of the counsel representing the Commonwealth in all matters before international judicial and arbitral tribunals.

The Solicitor-General also provides a substantial number of legal opinions each year in Commonwealth matters.

The Solicitor-General is assisted by two counsel assisting and also works in close collaboration with senior officers of the Attorney-General's Department, Australian Government Solicitor, other key departments and agencies and with leading counsel from the private bar.
