Quantum Tailored Finance Pty Ltd, previously known as WalterTurnbull Finance Pty Ltd, was established in 2003 as part of the WalterTurnbull Chartered Accountants Group of companies set up in 1992.

In June 2010, WalterTurnbull Chartered Accountants merged with PricewaterhouseCoopers, the largest Chartered Accounting practice in Australia. Part of the compliance work PricewaterhouseCoopers carries out had a direct conflict of interest with the broking business of WalterTurnbull Finance, now Quantum Tailored Finance Pty Ltd. It was agreed that Quantum Tailored Finance Pty Ltd would be an independent company.
