New pollie perks are exposed every day. So what are MPs actually entitled to, how do they record their expenses, and just how much is it all costing us? Crikey explains ... What are parliamentary entitlements? The parliamentary entitlements handbooks actually make it pretty clear: MPs have office, travel and accommodation entitlements set out in great detail. Limits on costs and types of payments are all articulated for senators and MPs. MPs are entitled to travels costs anywhere in Australia for "parliamentary, electorate or official business". Not pleasure. Not something an MP is attending in a personal capacity. The Department of Finance has made the information simple, attractive and clear. For example:

How do we know who spends what? Every six months, MPs and senators are required to submit their claims to the Department of Finance. Expenditure for January-June 2013 will be published later in the year. What can we learn about MPs from their entitlement reports? It is now common knowledge that the reports reveal the reading habits of MPs: who buys books (George Brandis); who buys only The Australian (Stephen Jones). The reports also tell us who gets the most traffic infringement notices -- or at least who thinks the taxpayer ought to foot the bill. Immigration Minister Scott Morrison charged the taxpayer for eight infringement notices for a car between July and October 2012 totaling $200. On September 16, 2012 Senator Nick Xenophon spent $1257 on a flight that was "not flown" and a "non-refundable fare". Xenophon was concerned about the figure, telling Crikey this morning that "something was wrong here -- the flight should have been cancelled as a matter of course". He is seeking clarification from the travel agent about why the fare was charged to the taxpayer. Gary Gray's report indicates he spent $488 on a Comcar in Perth on September 27, 2012 and appears to have paid back $1143 for a plane fare to Uluru on November 14, 2012. Gray was previously the special minister of state responsible for overseeing members' entitlements. Then there are the higher-end trends exposed by the members' reports. Four MPs -- Tony Abbott, Kevin Rudd, Tanya Plibersek and Adam Bandt -- spent more than $430,000 in 2012 on total office costs. That's almost double the average of $240,000 spent by members of Parliament including senators. The lowest spenders on office costs over the period included now retired Bendigo MP Steve Gibbons and Labor MP Rob Mitchell, who narrowly held his Victorian seat of McEwen. Costs are accrued over the financial year and cover leases, equipment and maintenance. MPs are not allowed to spend more than about $170,000 (depending on the size of their electorate) on office administration. Senators have a much lower cap on postage and printing costs. High-flying MPs: how much are they on the road? The reports are so detailed that it is also possible to map the movements of an MP over the period. Flight, accommodation and Comcar details can be extracted and pieced together to create a diary of a politician. The member for Corio Richard Marles held the position of parliamentary secretary for foreign affairs. A diary of his movements from July to December 2012 shows that he was away from his electorate (and family) for a total of 16 weeks -- or more than three out of six months ...
