A company run by a Federal minister who charged taxpayers $2000 a month for internet access lodged documents removing him as its director only after the matter was queried by The Weekend West.

Until late yesterday ASIC records showed Assistant Treasurer Stuart Robert was a director of an alternative health franchise business, despite Mr Robert telling Parliament a month ago he quit the board of Cryo Australia when he returned to the ministry.

Prime Minister Scott Morrison has ordered an investigation of revelations Mr Robert charged taxpayers more than $2000 a month for internet use at his Gold Coast home, far more than it costs any other MP.

Mr Robert blames the high charges on a poor home internet connection, forcing him to use a wireless service that charged extra for excess data use. Mr Morrison ordered a review of the charges, saying Australians would “want an explanation” why it cost Mr Robert more than $90 a day.

He said last night he would pay back thousands of dollars which he conceded were “much higher than what our community expects” from a politician. The Queensland MP quit as human services minister in 2016 over breaches of the ministerial code of conduct, after a probe of his business interests revealed he held shares in a trust linked to a Liberal donor.

He returned to the frontbench after Mr Morrison became PM. Mr Robert told Parliament he had sold shares and quit as the director of two companies.

But ASIC records show Cryo Australia lodged documents showing Mr Robert had quit as a director at 5pm yesterday, shortly after The Weekend West asked why there was a discrepancy between ASIC records and his parliamentary disclosures.

A spokesman for Mr Robert said the minister resigned from the board “with effect” from August 31.
