Expense documents show the $56,000 sidelined Speaker of the House Peter Slipper spent on airline travel in the second half of last year included a visit to New Zealand to discuss parliamentary procedures and art procurement.
The trip was taken when Mr Slipper was still Deputy Speaker.
In his letter to Special Minister of State Gary Gray explaining the two-day trip, Mr Slipper said he was interested in encouraging private benefactors to donate art for community display and wanted to learn how the New Zealand Parliament went about it.
He also met the former speaker of the New Zealand parliament to discuss parliamentary and question time procedures.
The bill was for domestic and international travel for the first six months of this financial year.
The documents also reveal of all the former prime ministers, John Howard spent the most on office facilities - just under $120,000.
