Law Council President John Corcoran made the announcement at this month's 36^th Australian Legal Convention in Perth.

Walker was nominated for his outstanding service to the legal profession and the wider community in his capacities as a community lawyer, barrister, senior counsel and philanthropist.

"Both his practice at the bar and his time spent giving pro bono assistance to a wide range of causes reflect both his incredible legal skill and deep understanding of people from all walks of life," Corcoran said.

"His commitment to social justice and his ability to interpret and apply the law at the highest level make him an invaluable member of the profession, as well of the wider community," he said.

A practising barrister for nearly 30 years, Walker has acted on many high-profile matters and he regularly advises the Australian Government on a variety of constitutional issues.
