The biggest commercial brokers in Australia unveiled!

In this second annual edition, we reveal the elite commercial brokers responsible for writing the largest volume of commercial mortgages and working capital loans in the country.

Topping the overall commercial ranking was Simplicity Loans & Advisory associate director Joshua Diab, who settled a massive $513.9 million in FY25 across 109 loans.

The Sydney-based broker specialises in complex property and development transactions across major banks, non-bank institutions, and private funds. His deals are often high-profile (and sometimes worth hundreds of millions of dollars), covering assets like shopping centres and major development projects.

Diab’s feat of being named the top Elite Broker – Commercial is even more impressive given he only started his career in 2019, joining Simplicity as office support.

However, when it comes to the sheer number of commercial loans settled, it was Son Pham from Rethink Financing who came out on top.

Pham, who was also named Commercial Broker of the Year at the Australian Broking Awards 2025, settled a huge 493 commercial loans over FY25.

Pham was also the only other commercial broker to have written more than half a billion dollars in loans over the financial year, demonstrating a rare combination of high volume and high value.

As was the case last year, a smaller proportion of brokers write working capital/cash flow loans. Of those who submitted, it was Brett Hartwig, CEO at Victoria-based brokerage BCP Finance, who wrote the most by value, settling around $40 million in FY25.

But William Hong from Talk to A Broker was the most prolific cash flow loan writer, having settled 79 cash flow loans over the year.

Special mention goes to Isabella Constantinou, also from Simplicity Loans & Advisory, who was the highest-ranked female commercial broker this year – and the only woman to make the prestigious top 10.

What unites all these elite commercial brokers is their mastery of specialised, high-value transactions. They exemplify that success in this sector requires not just raw volume, but an ability to efficiently structure and execute complex deals, leveraging deep market knowledge, specialised lending relationships, and operational efficiency to navigate the complexities of commercial finance swiftly.

Speaking of the ranking, Royden D’Vaz, the general manager, distribution and partnerships at Assetline, commented: “In commercial finance, timing and tailored solutions are critical.

“At Assetline Capital, we are committed to continually enhancing our commercial product offering, refining our processes, and investing in broker-focused tools to ensure you can deliver timely and reliable outcomes for your clients.
