Established by Tony Trevisan in 1980, the Transcontinental Group grew to operate substantial diversified businesses and investments in the mining and oil and gas sectors, and operate an Australian real estate development and investment business under TRG Properties Pty Ltd.
In 2018, the company changed its name to Tribis – reflecting a new era for the privately-owned business. At the same time, the company’s real estate arm was renamed as Iris Residential. Tribis has founded and managed a range of public and private companies.
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. It is understood that Roy Weston was sold to Harcourts in 2004.
