A Coalition MP is demanding the Federal Education Minister Simon Birmingham fix a controversial anti-bullying program or resign.

Senator Birmingham commissioned University of Western Australia Emeritus Professor Bill Louden to review Safe Schools earlier this month following complaints from Coalition MPs that the program, which teaches sexual diversity, was inappropriate for children.

Professor Louden presented his findings to a group of more than 30 Coalition MPs and senators on Tuesday night, but it appears it has done little to allay their concerns.

Queensland LNP MP George Christensen told the ABC he was not convinced the program should be kept.

Another MP who was at the meeting slammed the review as a "joke", telling the ABC that Professor Louden was given very limited scope, and just two weeks to examine the program.

He said Professor Louden visited just five of the more than 500 schools that offer the program and only examined the "official resources", not the suggested website links and supplementary reading.

"It has the appearance of an examination but it's just a fraud," he said.

"The Minister needs to fix this or resign."

The ABC understands Coalition senators are considering moving a motion in the Upper House on Wednesday to demand the Government withdraw funding for the program.

A spokesman for the Minister said the Government was considering its response and intends to release the findings publicly.
