Anthony Trevisan founded Transcontinental Group in 1980 and chaired the group until his retirement in 2018. He held senior executive positions in listed public companies with a wide range of interests including oil & gas, mining, industrial and property. These include Mediterranean Oil & Gas (founder and executive director, Ombrina Mare oil discovery), Arabex Petroleum NL (founder and executive director, Rubiales oil discovery), Callina NL (executive chair, petroleum work-over project at Komi Oil field, Russia), Aqua Vital Australia (executive chair, now owned by Coca Cola), TRG Properties (renamed Iris Residential following his retirement) and the Roy Weston Group (executive chair). He was a founding director of Star Castle Holdings and Brilliant City Holdings, and was responsible for their identifying and acquiring the Rio Pardo Project.
During the early eighties Mr Trevisan was responsible for introducing Target Supermarkets to Western Australia with major shopping centre developments in Kelmscott, Mt Hawthorn, Balga and Dog Swamp amongst others. As executive director of a leading property development company at that time he was also responsible for several other substantial developments in Western Australia including the regional shopping centre in Midland originally under the name of Swan City subsequently re-badged Midland Gate, and the office development at 200 Adelaide Terrace. Other significant interstate developments included a major role in the redevelopment of The Hoffnung site in the Brisbane central business district (CBD) and a substantial industrial development for Bridgestone in Victoria.
In the early nineties Mr Trevisan acquired the Roy Weston Real Estate Group and over the next 15 years he was responsible for growing that organisation into the largest real estate company in WA with over fifty five offices. Roy Weston was later sold (presumably to Harcourts, which acquired it in 2004)
