Euronet's Australian payments business, epay, went backwards for the seventh successive quarter late last year.Euronet first reported a reversal in transaction numbers in Australia in the June 2011 quarter, a theme echoed by the Kansas-based payments group each quarter since.This trend is hitting profits. In its December 2012 quarter financial report, released yesterday, Euronet said "adjusted operating income and adjusted EBITDA declined for both the full year and fourth quarter". This is partly because of lower sales in Australia, as well as in Brazil and Spain.NASDAQ-listed Euronet has turnover of around A$200 million from its Australian subsidiary.The loss of contracts with a couple of Australian telecommunications companies to supply recharge services is behind the decline in volume.In January, Euronet extended its reach in Australia with the takeover of niche payments' processor Pure Commerce.
