Smaller banks are doing a better job of keeping customers happy than the big four.
ING Direct has been voted Australia's best bank in an online survey of customer satisfaction by comparison website Mozo.com.au.
In state-by-state rankings, only South Australia included major banks in their top five for customer satisfaction.
ME Bank scored the title of best home lender, as well as provider of credit and debit cards.
Despite being pipped by their smaller competitors, the big four did enjoy an all-time high satisfaction rating of 7.55 out of 10.
Record low interest rates had ushered in a "new golden era" for banking satisfaction, Mozo director Kirsty Lamont said.
"With rates at all time lows ... the battleground will shift towards customer service, convenience, brand trust as well as pricing."
But Generation X bucked the overall trend of greater satisfaction with banks - due to the higher rate of debt carried by those aged 35-54, she said.
This is the fourth year Mozo.com.au has run the awards, which are based on 28,000 customer reviews.
