The ABC has once again been accused of biased reporting by a federal MP taking out an ad in a local newspaper.

Queensland Liberal Nationals MP George Christensen has admitted to using his taxpayer purse to criticise the ABC's coverage of the state's new Adani coal mine.

Christensen is the second federal MP to use taxpayer funds to attack the public broadcaster in recent days. Last week, Labor backbencher Michael Danby paid for an ad in the Australian Jewish News which claimed people have a "distorted understanding" of Israel thanks to the ABC.

The broadcaster, at the time, took the rare step of slapping down the ad, calling it "inaccurate" and part of a series of "inappropriate attacks" aimed at its Jerusalem correspondent Sophie McNeill.
