Northwest Tasmania is facing yet another round of political musical chairs, with state MP Adam Brooks quitting parliament less than a year after being re-elected and six months on from a federal by-election in the region.
The Liberal MP, who courted controversy as mining minister, confirmed his departure on Monday following questions about his business interests.
A recount of the Liberal ticket from last March's state election is expected to parachute former MP Joan Rylah into the vacancy.
The shuffle comes just six months after voters for the federal seat of Braddon went to the polls for a by-election after the resignation of Labor's Justine Keay.
Ms Keay, who had quit amid questions about her citizenship, was re-elected.
Mr Brooks, who has been on long-term leave, cited health and family reasons for his departure.
"I will be resigning from parliament. I do this with extreme sadness as it has been a privilege and an honour to serve the people of Braddon for the past nine years," he told Tasmania Talks on Monday.
"I can't at the moment give 100 per cent to the community of Braddon.
"I was hoping with this recess I could get myself back into a good enough shape where I could meet the expectations that I set myself to deliver for the community."
A two-year investigation previously cleared Mr Brooks of a conflict of interest over use of an email account linked to his mining software business while mining minister.
But the Integrity Commission found Mr Brooks misled Premier Will Hodgman and deleted emails partly because he thought they could be damaging.
Speaking after the resignation, Mr Hodgman did not shy away from the controversy which dogged Mr Brooks' time in politics.
"Adam's career, like everyone else's, has never been perfect. He has made mistakes, he's acknowledged that, he's been very public in apologising," Mr Hodgman told reporters.
Tasmania's Labor opposition welcomed news of Mr Brooks' departure.
"We did not believe Mr Brooks upheld the standards expected of members of parliament and that his position was untenable since the release of the Integrity Commission report," Labor MP Shane Broad said in a statement.
The state and federal divisions of Braddon share the same boundaries and take in the centres of Devonport, Burnie, Wynyard and Ulverstone, as well as the state's west coast.
