In 1881 he was articled to Charles James Cresswell in Hamilton, and from 1885 to David Houston Herald in Melbourne, being admitted as a barrister and solicitor on 1 September 1886.

[1] Cameron married Mary Wright on 29 June 1892 in the Toorak Presbyterian Church, with the two subsequently living in Malvern.

[1] Cameron's candidature for Town of Malvern's South Ward was announced on 5 July 1902,[3] a position he subsequently won on 28 August 1902.

[8] Construction was authorised in July 1908,[9] and began on the first two routes on 20 October 1909, with both lines opening to the public on 30 May 1910, operated by 13 trams.

[5] By 1920, when the PMTT was absorbed into the Melbourne & Metropolitan Tramways Board (MMTB) the PMTT had sixteen lines; 94 operational trams; and served passengers in multiple suburbs beyond Prahran and Malvern, including Camberwell, Caulfield, Caulfield South, Point Ormond, Glen Huntly, Hawthorn, Kew, Kew East, Mont Albert, St Kilda, and Victoria Bridge (Richmond).

[1][5] Much of the growth and success of the PMTT is attributed to Cameron, who became a "recognized (sic) authority on the subject of passenger transport".

[12] He was thanked for his service with the gift of a leather smokeroom chair, and HS Dix was selected to serve the remainder of Cameron's term.

[1][2] Under Cameron, the MMTB soon opened the Fitzroy, Northcote & Preston Tramways Trust and Footscray Tramway Trust lines,[2] constructed a new link connecting the northern electric lines, built the Preston Workshops, and commenced construction of the now iconic W class trams.

Twenty routes were either opened or extended under Cameron,[22] and he is credited with building tram lines in largely unpopulated areas where future development was anticipated, creating a network that "thickly populated" Melbourne's suburbs.

[2] This astute management saw the MMTB have balanced books, with the exception of the first four years, with large amounts made available for infrastructure investment.

[27] Cameron's five-year term as chairman of the MMTB was repeatedly extended, postponing a review of the boards structure.

[1][11] This move was objected to by other members of the board, who "protested at the grave discourtesy shown to him" and "paid tribute to him when he chaired his last meeting on 19 December.
