SYDNEY (AFP) - Australian Prime Minister Tony Abbott was embroiled in a spiralling travel expenses scandal on Tuesday as he defended his use of taxpayer money to take part in an ironman competition and other events.
The issue has blown up for Mr Abbott, who was elected to office last month vowing to lead a government that would "live within its means", while in Indonesia for the Apec summit.
Last week he voluntarily repaid about A$1,700 (S$2,000) in travel expenses claimed for attending the weddings of two former colleagues in 2006.
He did so following uproar after two senior members of his coalition were heavily criticised after being exposed for billing taxpayers thousands of dollars to go to the wedding of a radio host.
One of the weddings Mr Abbott claimed for involved former parliamentary speaker Peter Slipper, who he vigorously pursued last year over his alleged misuse of taxi vouchers to visit Canberra wineries, sparking accusations that the prime minister was hypocritical.
On Tuesday, Australian media also revealed Mr Abbott, who has a macho reputation, charged taxpayers almost A$1,300 in travel and accommodation costs to compete in a 2011 ironman event, in which you run, ride a bike and swim.
He also routinely claimed a travel allowance and flights to take part in the annual 1,000 kilometre Pollie Pedal charity cycling trip through regional Australia that lasts several days, it was reported.
Mr Abbott insisted on Tuesday it was "perfectly legitimate" for the public to pay for travel expenses for his participation in charity and community sports events.
"I believe that all of my claims have been within entitlement," he told reporters on the Apec sidelines, adding that "the great thing about Pollie Pedal is it takes me to towns, communities, sometimes hamlets that rarely see a politician".
But with the furore growing, he admitted: "People should be careful and cautious when they claim entitlement. If there is any doubt they should resolve the doubt in favour of the taxpayer."
In an editorial, the Sydney Morning Herald said Mr Abbott's government needed to lead by example having come to office promising no excuses, "but now they are coming thick and fast".
"When there is doubt, surely taxpayer interest beats the personal one," it said.
Mr Bill Shorten, who is campaigning to be Labor leader following Mr Kevin Rudd's defeat to Mr Abbott in October elections, said the system needed to be tightened.
"I don't think most MPs - the vast, vast, vast majority - are out to do anything wrong," he told ABC radio.
"But if there is this confusion and there is this uncertainty, then it does need to be cleaned up for the public confidence in the system, full stop - it does need to be sorted."
