He was also a clerk and bookkeeper at his mother's law firm Travers & Keogh, where he later worked as a solicitor from 2005 to 2006.

He joined the Commonwealth Director of Public Prosecutions as a prosecutor in 2006, before moving to private practice in 2011 as a commercial lawyer with Herbert Smith Freehills.

[4][5] After being unsuccessful as Labor's candidate at the September 2015 federal by-election in Canning,[6] which precipitated Malcolm Turnbull deposing Tony Abbott as Prime Minister of Australia, Keogh ran successfully in the 2016 federal election for the electorate of Burt.

However, it included much of the more urbanised portion of the old Canning, and much of the seat's territory was represented by Labor at state level.

[citation needed] Following his election in 2016, Keogh was elected the deputy chair of the Labor Caucus, appointed the Labor Opposition Waste Watch spokesperson and became a member of the House Economics Committee, which was tasked with inquiring into the Australian banks,[7] as well as the House Agriculture & Water Committee and the Parliamentary Joint Committee on Corporations and Financial Services.
