Sir Walter "Wally" Benjamin Campbell, AC, QC (4 March 1921 – 4 September 2004) was an Australian judge, administrator and governor.

[2] Archie Campbell was a decorated soldier of the First World War, having won the Military Cross for gallantry in action against the Ottoman Turks in Gaza and the Distinguished Service Order for later efforts in Damascus.

[4] The death of his mother interrupted Campbell's early education at a Christian Brothers' convent in Toowoomba and led to his continuing his studies at a college in Lismore, New South Wales.

He became President of the University of Queensland Union, and graduated in 1948 with first class honours in Law, having already gained a Master of Arts the previous year.

[15] The issue of lawyers being unwilling to move from the Bar to the Bench remained a concern to Campbell even after he had left the judiciary and become governor.

[16] Campbell became the centre of a controversy, as he was chosen to fill the Chief Justiceship instead of Jim Douglas, the favoured candidate of the Liberal Party.

[16] Campbell emerged largely unscathed from the controversy, but did clash at times with the Bjelke-Petersen government as Chief Justice, criticising the legal integrity of certain legislation when he found it necessary.

There had already been murmurs in early 1987 of a vice-regal intervention in Queensland politics when The Australian newspaper in March featured a front-page article detailing State Opposition leader Nev Warburton's call for Campbell to sack Bjelke-Petersen over allegations of illegal conduct by the government.

However, later in the year when Bjelke-Petersen lost the confidence of his cabinet, the question was again raised as to what role Campbell as governor would play in the event of a constitutional crisis.

[24][25] Some sections of the press attacked Campbell for his apparent inactivity during the crisis, while other voices within the legal and political world supported his course of action.

[29] In March 1988, Campbell gave a lecture on "The Role of a State Governor" to the Royal Australian Institute of Public Administration, Queensland Division, in which he described the various functions carried out by state governors, the legal and constitutional framework of the office and numerous historical accounts of different situations involving vice-regal figures in Queensland and other Commonwealth domains.

[30] He did not retire quietly, continuing to speak at various functions and publicly opposing Paul Keating's push for an Australian republic in 1993 by writing to the British newspaper The Daily Telegraph.

[33][34] He resided with his family in Clayfield, Brisbane while a member of the Supreme Court judiciary and retired to Ascot after leaving Government House.
