He had his first property at 19, doubled the investment in 18 months and is now one of Australia's wealthiest people with a fortune of A$866 million ($902m).
But Jonathan Hallinan says it's lonely at the top. "It's insulating," he told The Weekend Australian after coming in at number 112 on the newspaper's inaugural list of the nation's 250 richest individuals. "People see really successful people as the successful people that they'd love to be, but to be incredibly successful at any one thing, you're actually living a very insulated life.
"You're not necessarily worldly … you're not life experienced. My friends who have nothing are far more life experienced than I am."
Hallinan appears in The List — Australia's Richest 250 in today's Weekend Australian. The 43-year-old is the founder of property group BPM, which has residential and commercial developments in Brisbane and Melbourne, and he's now working on projects in Los Angeles.
He also owns men's suiting business The Cloakroom, which has boutiques in Melbourne, Brisbane and Tokyo and is about to open another on the top floor of BPM's Shadow Play development in Melbourne, alongside a bar.
