The real estate industry has recognised Kollosche principal Michael Kollosche and sales agent Troy Dowker as being among the best in the business, with both ranking in its exclusive list.

The Real Estate Business (REB) Top 100 Agents National 2025 placed Michael at No.13, with Troy coming in at No.52.

Michael settled $594,316,500-worth of property – the third-highest sales volume of any agent in Australia in the 2024-25 Financial Year – and achieved the highest average sale price nationally of $6,530,951 across 111 sales. This helped cement his overall ranking.

He was joined by fellow agent Troy Dowker who ranked at No.52 in the Top 100 list, achieving an overall sales volume of $268,400,388 across 61 settlements with an average sale price of $4,400,006.

These placings follow the release of the REB’s statewide list of Top 50 agents where Michael ranked No.2, with Troy at No.10 and fellow agents Jamie Harrison and Rob Lamb also ranked at No.30 and No.37, respectively. Jamie posted $176,477,000 across 37 sales for an average $4,769,649 and Rob had 36 sales achieving a total volume of $132,241,600 at an average $3,673,378.

Now in its fifth year, the REB Top 100 National and Top 50 QLD lists acknowledge those agents who are setting the benchmark for excellence among their peers based on a dedication to customer service and strong sales numbers in their local markets.

The rankings are determined using a range of metrics, including number of properties sold, total dollar volume of properties sold, average sale value, number of support staff and years in the industry.

Nationally, the Top 100 agents transacted $25.82 billion-worth of property – a 15.3 per cent lift on the previous year’s results. The average sales price nationwide lifted $100,000 to $2,410,580, and the number of settled properties rose from 111 to 117.
