Tony Abbott told to act after Don Randall in hot water over expense claims for Cairns trip WA Liberal Don Randall is the latest MP to be caught up in a travel expenses scandal. PRIME Minister Tony Abbott is under mounting pressure to overhaul parliamentary expenses after the latest case, this time involving one of his own West Australian Liberal MPs. Opposition Leader Bill Shorten this afternoon called for an overhaul of the rules following revelations Canning MP Don Randall claimed than $5000 for himself and a family member to travel to Cairns on "electorate business" in November last year. The trip came a week before he declared to parliament he had taken possession of a new investment property in the tropical far north hotspot. Mr Randall, who has declined to comment, also claimed "for sittings of parliament" in September last year, despite him making the claim for being in Melbourne and the date claimed for his $371 travelling allowance being a Saturday.

Records show Mr Randall flew from Melbourne to Canberra for the start of the sitting week but his family member flew back to Perth. Mr Shorten said: "I firmly believe it's worth considering a simplification or clarification of the rules to ensure the public's confidence in the system. I'd call on the Prime Minister to outline his plans on the issue. Labor is open to working with the government on any constructive proposals that would resolve ambiguities or complications in the entitlements system. Comment has been sought from the PM. Some of Mr Randall's other claims included billing taxpayers for more than $2000 worth of mobile phone calls while on an overseas study tour to Sri Lanka with his wife. He also claimed books including the Guinness Book of World Records and cook books. Contacted by News Corp Australia this afternoon, Mr Randall's office was asked whether he had a legitimate excuse but it declined to comment.
