Former federal parliamentary speaker Peter Slipper will call evidence about Prime Minister Tony Abbott's use of travel allowances in an appeal against his conviction for dishonesty, court documents have revealed.

Slipper is due to be sentenced later this month, after being found guilty in July of misusing his Cabcharge allowances to visit Canberra wineries in 2010 before he was speaker.

But he has already lodged an appeal and has signalled he will use press reports about Mr Abbott's repayment of travel costs after he attended former MP Sophie Mirabella's wedding in 2006.

Last year the Prime Minister repaid more than $1,000 in taxpayer-funded travel expenses he claimed when he attended the wedding.

Slipper will also call on evidence about other MPs allowed to pay back travel money to which they were not entitled.

Slipper has always questioned why his case was taken to court and he was not simply allowed to pay back the money.

The ACT Magistrates Court found he had falsely recorded his travel during three trips.

The total bill for the trips was believed to be just more than $900.

On the first occasion in January 2010, Slipper visited up to six premises including the prestigious Poachers Pantry and Clonakilla wineries.

A hire car driver gave evidence that he drove Slipper and another man to several wineries and at the end, Slipper asked him if they could split the payment up into four amounts "because it would make processing easier".

The court also heard evidence from a second hire car driver, who drove Slipper to wineries on two other occasions.

The latest court documents come after James Ashby last night revived unrelated claims on national television that Slipper sexually harassed him, along with fresh allegations about the involvement of Coalition MPs in the lead-up to his legal action.
