Tasmanian Opposition Leader Rebecca White has defended her actions against a Labor candidate over claims he sent inappropriate text messages to a workmate seven years ago.
Labor state president Ben McGregor has abandoned his bid to challenge the seat of Clark in the May 1 poll after being accused of sending questionable messages to a public sector colleague in 2014.
Ms White has sided with the woman who claimed to have received the message.
Mr McGregor apologised for the message at the time and is planning defamation action against Ms White for her comments on the matter, The Hobart Mercury newspaper reported.
The opposition leader says she took the woman's allegations seriously and acted decisively, despite the potential political ramifications.
"Those things are evident for the community to see, as to what decision I took and the action that I took," she told reporters on Sunday.
Liberal Premier Peter Gutwein pounced on the scandal, saying it offered an insight into how Labor would run the state.
"The chaos and dysfunction continues," he told reporters in Launceston.
"The way that they manage themselves through a campaign, I think people can make a judgement, that's the way that they would manage themselves if they would have become the government."
Ms White took aim at Mr Gutwein for failing to act against Liberal candidate and former MP Adam Brooks, who is due to face court over alleged firearms storage offences.
"Peter Gutwein needs to explain to the people of Tasmania what standard he expects his candidates to meet, and for them to be elected to public office," she said.
"In my view Adam Brooks is not an appropriate person to stand for election to the Tasmanian parliament."
In its latest election pledge, Labor on Sunday promised to invest $167 million in 144 extra paramedics, and upgrade ambulance stations across Tasmania, along with 10 new extended-care GP centres.
"We know that heart attacks don't book an appointment, and it can be impossible for people to get into seeing a doctor sometimes," Ms White said.
"Having an ambulance to respond in time is the best way to keep patients safe and to make sure our community gets the health care they deserve."
The premier promised a majority Liberal government would spend $8 million over four years on dredging the state's northern Tamar River.
"We're going to fix this. It's not acceptable, the state of the river at the moment," Mr Gutwein told reporters.
However, the premier pushed back against criticism that his pledge was pre-empting advice in a pending Tamar Estuary Management Taskforce report.
The premier also pledged $4 million over four years on skills training for workers in the construction and civil infrastructure sector.
