Big four banks vs other lenders: Who has the best interest rates?
Based on Money.com.au’s analysis of a wide range of current mortgage rates, smaller lenders tend to have lower interest rates than the big four banks. However, it will depend on your loan type and loan-to-value ratio (LVR). Lower LVRs typically mean lower rates and higher LVRs mean higher rates.
Mansour Soltani, Money.com.au's Home Loans Expert
“Smaller lenders typically operate with lower overhead costs and tend to offer lower rates to compete for market share against the big four banks. So, if you’re a borrower chasing the lowest rate possible, we’d maybe suggest going with a smaller lender. On the flip side, if your LVR is sub 60-70%, you’d probably get a good rate from one of the big four. There may be cases where one of the big four don’t have the best rates, but have policy tweaks suitable to your borrower scenario. For example, ANZ will accept one year of financials for business owners, while most other lenders require two years’ worth. NAB doesn't ask for a detailed breakdown of expenses if you withdraw over $100,000 in equity, unlike some other banks.”

How satisfied are Australians with the big four?
According to the latest Roy Morgan banking customer satisfaction ratings, Westpac has the highest home loan customer satisfaction among the big four banks, with a rating of 73.6%. The average customer satisfaction for home loans among the big four banks as a collective is 71.8%.
CommBank and NAB came second with a 73.5% satisfaction score, followed by ANZ at 66.7%. Customer satisfaction is measured on a scale of ‘very satisfied’, ‘fairly satisfied’, ‘neither satisfied nor dissatisfied’, ‘fairly dissatisfied’ and ‘very dissatisfied’.
Are Australia’s big four banks safer than other lenders?
The big four banks are generally no more or less safe than smaller lenders. The Australian Prudential Regulation Authority (APRA) and the Australian Securities & Investments Commission (ASIC) regulate all registered financial institutions, regardless of their size.
Additionally, any bank that accepts deposits from the public – known as authorised deposit-taking institutions (ADIs) – is covered under the Financial Claims Scheme (FCS). Under this scheme, if a lender was to collapse, the government would guarantee up to $250,000 of your money (per account holder, per institution).
Some smaller lenders are in fact divisions or subsidiaries of one of the big four. For example, UBank is backed by NAB, while St.George, Bank of Melbourne, BankSA and RAMS are under the umbrella of the Westpac Group.

“There’s definitely a misconception that going with a smaller lender is risky because they may go bust. No banks have gone bust in Australia. In the unlikely event of a lender collapse, a larger bank would likely acquire its customer and loan portfolio and your mortgage would get sold to that larger bank.”
