A federal Coalition MP charged taxpayers to attend last year's Bledisloe Cup, listing the Brisbane game as a "sitting of Parliament" on his expenses claim.

Queensland Liberal National MP Ken O'Dowd also charged the cost of bringing a family member to the final match of the annual Australia versus New Zealand rugby series.

According to Mr O'Dowd's publicly available register of interests, oil and gas giant Santos gave him two tickets to the game, played at Brisbane's Suncorp Stadium on October 18.

But an analysis of Mr O'Dowd's latest six-monthly expense report reveals taxpayers picked up an almost $2100 expenses bill.

While the backbencher usually travels from his home base of Gladstone to Canberra in a single day for parliamentary weeks, this time he left a day early and spent a night in Brisbane en route.
