Queensland's police minister has denied manufacturing official business for a personal trip to Cairns so he could claim it on the public purse.
Jack Dempsey was asked last week in budget estimates whether he instructed staff to prepare official business for a trip he had already planned to Cairns in May last year so he could use his government travel allowance.
Mr Dempsey told reporters on Tuesday he had planned to travel to Cairns to watch his son play football before he had even been sworn in as minister.
But he said after becoming police minister, he decided to make the most of the trip, which was common for ministers whenever they travelled.
Given his new ministerial commitments, he only saw his son play for about half an hour, he said.
Mr Dempsey labelled the estimates questioning as a Labor party stunt.
"It's indicative of the Labor party trying to involve your family in the political spectrum and it's really poor in that aspect," he said, referring to the campaign against Premier Campbell Newman at the last election.
Labor's Bill Byrne put it to Mr Dempsey during estimates that an email from an advisor to police media days before the trip requested whether there was a "quick event we can throw together for this?".
Mr Byrne is now calling for Mr Newman to intervene and demand a full explanation from his police minister.
"If there is not a viable explanation, the Premier must ask Mr Dempsey to... resign," Mr Byrne said in a statement.
But Mr Newman has already backed Mr Dempsey, telling reporters on Monday his minister was simply "getting going in the job".
