Darren McCormack, Principal Finance Broker at Mayfair Finance Australia
Darren McCormack — Finance Broker & Principal, Credit Representative No. 435607
The Broker, Not the Bank

He was trained to think like a lender. Now he works for you instead.

Darren has been in the finance industry since 1989 — with senior roles at Westpac Banking Corporation in Australia, and at Barclays Bank and National Westminster Bank in London. That's three of the world's largest banks, and a rare vantage point on exactly what a credit committee is looking for before they say yes.

In 2013 he founded Mayfair Finance Australia to put that experience to work on the client's side of the desk — testing the market on your behalf across more than 50 lenders, rather than defaulting to the first approval that comes back.

Business loans, overdrafts, debtor finance and commercial property lending, structured around how your business actually operates.

03

Vehicle & Equipment Finance

Business vehicles approved within hours, equipment finance within 48 — built for owners who can't wait weeks on a bank queue.

04

SMSF & Property Development

Better Business Awards — Mayfair Finance Australia
Multi Award Winner

Recognised across multiple categories for service and client outcomes — the same standard Darren brings to every file, from a first home buyer to a $6.5m business refinance.

Proof, Not Promises

Every 2–3 years, we test the loyalty your bank is counting on.

Our Debt Portfolio Review takes 15 minutes and typically uncovers $3,000–$15,000 a year in savings on home lending, and $10,000–$110,000 a year on business finance.

Our record result: a client who'd stayed loyal to one bank for over 20 years — we renegotiated their pricing and kept the relationship entirely intact.
