Federal politicians claimed more than $55 million in expenses over the second half of 2015, new documents have revealed.

Among the latest figures on parliamentarians' entitlements published by the Finance Department was a $60,282.75 bill for "accommodation and meals" charged against former prime minister Tony Abbott between September 25 and 27 last year.

The expenses are listed as being for a trip to the United States, but Mr Abbott never got to make the journey after being removed as prime minister by his Liberal colleagues the week before.

Foreign Minister Julie Bishop claimed the largest amount with a total of $808,649.49, more than half of which was for overseas travel in her ministerial role.
