National Australia Bank's physical presence in retail shopping centres and commercial streetscapes is fading as it decommissions hundreds of proprietary ATMs across the country.The bank confirmed to Banking Day on Tuesday that it had culled its branded automatic teller network by around 200 machines in the last year in response to the customer shift to cashless modes of paying.At the end of May, the cull had reduced NAB's fleet of branded ATMs to only 1200.In recent years, the bank has not disclosed the size of its proprietary fleet, electing instead to disclose a combined tally that included agency ATMs that its customers could use without incurring fees.NAB appears to have accelerated the withdrawal of branded ATMs in Victoria in recent months, particularly in the northern suburbs of Melbourne.A bank spokesperson said the reconfiguration of the network was being driven by abrupt changes in customer behaviour."The way our customers are using ATMs is changing fast, with more customers doing simple and free withdrawals using eftpos and at thousands of fee-free ATMs across Australia," the spokesperson said.Cash withdrawals at NAB ATMS have declined by 12.5 per cent in the last 12 months.While the other major banks are also expected to scale back their fleets, official ATM statistics published by the Australian Payments Network indicate they are delaying their culls.There were 31,712 ATMs in Australia at the end of March - a decline of only 467 compared to the same time last year.While NAB is now operating a thinner fleet, it has upgraded one third of its proprietary network to new generation SmartATMs.
