Cardinal George Pell has dismissed a Greens motion in the Senate calling on him to return to Australia to aid a police investigation into misconduct as a "political stunt".

Cardinal Pell, who was interviewed by detectives from the Sano Taskforce in Rome in October, also said he believed that "fair minded Australians" would see Wednesday's motion calling on him to return to Australia as "point-scoring".

The statement, released to News Corp overnight, reportedly said the Greens were well aware "of the cardinal's decisive actions to address the evils of abuse and the changes he has implemented in the church over 20 years ago".

"Their anti-religion agenda is notorious and most fair minded Australians would see this motion as pathetic point-scoring."
