How the business is structured
Who owns it, who licenses it, who answers for itQuantum Finance Australia Pty Ltd trades as Quantum Finance Australia and holds Australian Credit Licence 389083. Gavin Harrigan founded the practice in 2005 and still runs it.
That structure is the whole reason the recommendation can be about your file. A franchised broker sits inside somebody else’s business, with preferred lenders and volume agreements attached. None of that applies here.
What each part of the arrangement actually does for you is set out below, and the step-by-step version of the work is on the loan process page.
Independently owned
No franchise agreement, and no lender holds a share of the business. There is no head office setting a monthly target and no brand upstairs to keep happy.
Licensed in its own right
Australian Credit Licence 389083 belongs to the business, which means the responsible lending obligations attached to it are owed to you by us.
One office, three brokers
Everyone works out of West Leederville. The broker who takes your first call prepares the application, and reviews the loan two years later.
Aggregated for reach, not for direction
MoneyQuest handles lender accreditation and settlement plumbing. It does not choose your loan and it has no say in the recommendation.

Who this practice works with
The files that come through the doorPerth-based for the most part, with expat clients spread across time zones. Lending is subject to approval and to your circumstances in every case.
