Harry Oskar Triguboff AO (born 3 March 1933) is an Australian billionaire real estate developer, and one of Australia's richest people.

[4] Triguboff's net worth was assessed at A$11.62 billion in the 2016 Rich List, making him the richest Australian;[5] yet held the mantle for only one year.

The foreign concessions were initially left untouched, but following the invasion of Pearl Harbor in 1941 the British and American residents were placed into internment camps.

[11] In 1946, Triguboff's family obtained landing permission for Australia, after being refused visas to Canada and the United States.

He and his brother were sent to Sydney in 1948, but the Australian government attempted to exclude them from the country over concerns about their father's war-time activities.

Osmond Charles Fuhrman, the Australian consul in Shanghai at the time, estimated that their father had a net worth of up to US$4 million (equivalent to $51,000,000 in 2023).

At Meriton Street, Triguboff built a block of 18 units which provided the name of the company he registered as developers.

[15] In particular, Triguboff has concentrated on the Gold Coast and Brisbane in Queensland, and Sydney's central business district, building more apartments than any other Australian residential developer.

During 2012, Meriton and the owners' corporation became embroiled in a long running court dispute over major building defects and alleged breaches of their contract, with maintenance issues worth more than A$1 million.

[24] In June 2023, under Triguboff, Meriton renewed plans to build up to 1,600 homes in Little Bay near Sydney, on land it had previously purchased for around $250 million.

[31] In December 2024, he appeared on the Straight Talk with Mark Bouris podcast and warned that Chinese migrants may take over Australia.

In August 2010, he proposed that the federal government should insist on Reserve Bank interest rates being dropped to improve housing affordability.

[citation needed] According to the 2023 Financial Review Rich List, Triguboff's personal net wealth was estimated at A$23.80 billion.
