Mobile access to banking has boosted people's awareness of of their financial situation and helped prevent them going into the red, according to research by Westpac bank.
The online survey of 843 Westpac customers confirmed expectations that the trend to use a smartphone or tablet to check your accounts is being taken up widely in the younger and more affluent crowd.
Of those surveyed 84 per cent of 26 to 35 years olds used mobile banking and 78 per cent of under 25 year olds used it.
But, surprisingly, 30 per cent of people aged over 55 also used their devices to bank.
Those earning over $50,000 a year were also more likely to use mobile banking.
