Federal government MP George Christensen has accused a former "senior government MP" of being behind a "vile and hateful smear campaign" over his frequent trips to South East Asia, pushing the Morrison government back into another political controversy days before Christmas.

Damaging any hope the government had of finishing the year on a positive note, Mr Christensen outed himself on Saturday as the subject of days of allegations involving trips and money transfers to areas associated with red light districts in the Philippines.

Mr Christensen said he had confirmation from the Australian Federal Police (AFP) that found there was "no evidence, or other information to support the allegation, or establish criminal conduct,” and, as such, they did not launch any investigation nor did they, at any stage, interview him about any matter, criminal or otherwise.

The Queensland MP has not released the AFP advice publicly.
