However, he later asserted that he had made no travel claim for that wedding.
In what can only be described as a politically dark twist the Prime Minister, who as Opposition Leader relentlessly pursued the then Speaker Peter Slipper in relation to alleged parliamentary entitlement rorts, has admitted claiming travel expenses as a minister in the Howard Government for attending Slipper's 12 August 2006 wedding:
TONY Abbott has quietly repaid $609 in taxpayer-funded entitlements he claimed to attend the 2006 wedding of one-time colleague Peter Slipper....
The then Federal Treasurer Peter Costello was also one of the 200 plus guests at the Slipper wedding and claims that he was reimbursed for travel expenses as he had official business in Brisbane during that period. While fellow guest the then Attorney-General Phillip Ruddock is firmly stating that he has no intention of repaying expenses claimed as Slipper was a work colleague.
Minister for Immigration and Border Protection Scott Morrison at first flatly denied he had claimed travel expenses to attend the the wedding of WA Liberal MP Steve Irons, but soon had to join Assistant Minister for Defence Stuart Robert in repaying money for that particular 21 October 2011 event.
Stung by the public reaction to these disclosures, Coalition Government members are busy ferreting though the expense claims of the Labor Opposition and, thus far it has been relatively slim pickings.

In November 2012 Liberal Party Member for Canning Don Randall and a family member flew from his home state of West Australia to Cairns in Queensland on unexplained "electoral business" which may have been connected with his investment property there - billing the taxpayer $5,259 for this trip and apparently charging multiple associated taxi fares to the public purse as well.
