PETER Slipper appears to have a long history of being loose with his taxpayer-funded Cabcharge account.
A former Sunshine Coast cabbie has revealed how he picked up a girl in Mooloolaba who paid for her fare using a blank Cabcharge docket from Mr Slipper's office.
The transaction happened late on Saturday night on October 23, 2010.
The former cabbie, who asked to remain anonymous, said he thought it was "strange" at the time.
He has come forward now as more allegations of Mr Slipper signing blank Cabcharge dockets have been disclosed.
"She got in the cab and it was obvious she'd never had a Cabcharge docket in her life," he said. "She said, 'I've got a Cabcharge docket, is it okay to use?'"
He said the docket was to be charged to Mr Slipper's office.
"She said she got it from a flatmate who used to work with Peter Slipper," the cabbie said.
The former taxi driver said that a Cabcharge docket was "all we need as cab drivers" to pay for the fare.
"It's a piece of paper that is signed - it is the same as its weight in gold.
"The girl wasn't even an ex-staffer.
"She said she got it from an ex-staffer who left."
Suncoast Cabs was unable to confirm yesterday that the document was from Mr Slipper's office.
However, it might explain how Mr Slipper, who was forced to step aside from his role as Speaker this week, has been able to allegedly incur taxi fares in one part of the country while he was on business in another.
Using Freedom of Information, a Sydney newspaper found that Mr Slipper took a taxi trip on June 1 in Townsville, but he was in Canberra on the date the taxi fare was booked.
The allegations came as Mr Slipper continued to face pressure over the alleged sexual harassment of a former staffer James Ashby.
Mr Slipper did not return the Daily's calls yesterday.
The Department of Finance has also declined to discuss any possible investigation into Mr Slipper's use of travel expenses.
"Allegations of misuse of Parliamentary entitlements are generally considered in accordance with the Minchin Protocol," a spokeswoman said.
"It is not appropriate to comment on any particular matter that may or may not be under consideration at any given time, as to comment may compromise the conduct and outcome of any inquiry."
