A NSW MP who billed taxpayers to watch Disney, thriller and romance movies on Foxtel could not prove the expense was required for his job in Parliament, the state's Auditor-General has found.

The unnamed film buff is among a raft of politicians who failed to comply with rules governing their monetary perks of office, according to an audit of 43 MPs released on Thursday.

NSW MPs enjoy a generous base salary of $149,541 – twice the average wage – plus payment for ministerial or office-holder responsibilities and expense allowances.

One MP claimed a monthly Foxtel subscription including a "Deluxe Movie" business package add-on. It includes world, comedy, action, thriller, romance, and Disney films, among others.

Deluxe movies presently showing include101 Dalmations, The Lego Movie, Sex And The City and Romy & Michele's High School Reunion.
