The Mirren Team

Rene Marzinger


  • Finance Planner
  • Buyers’ Agent and Mortgage Broker
  • Engineer
  • Professional Investor

Mirren founder Rene Marzinger has worked in 27 countries in his lifetime – but there was something about Australia that kept him here.

“Australia is the best country in the world. I just love the people here … the laid-back, casual culture.”

South African born Rene was a brilliant young engineer when he left his country to work, explore and live. But after arriving here, he realised something that set Australia apart.

All of the most successful people in Australia have property … because of the property tax laws. Those people effectively used their property portfolio as a foundation and built their wealth from there,” he says.
