Just half an hour before the official Declaration of Poll ceremony at Devonport's paranaple Centre, Premier Peter Gutwein announced the resignation of Adam Brooks, the fifth elected member for Braddon.

He also revealed Mr Brooks was in Queensland receiving mental health treatment.

Mr Brooks had ended 312 votes ahead of fellow Liberal Felix Ellis on Thursday, and Mr Ellis posted his acceptance of the results to social media last night.

Despite this, political veteran Jeremy Rockliff smoothly kicked off the speeches, gladly accepting his sixth successful election campaign for Braddon.

"At the end of the day, we're there to do the best that we can to represent our community," he said.

Labor's Anita Dow, the second member for Braddon, said she felt "privileged" to be chosen to represent Braddon once more.

She added that she was looking forward to working with the other members, taking a moment to particularly thank Felix Ellis.

"I think we might be seeing him again in the future," she hinted.

Labor's Shane Broad echoed sentiments that the entire process had been "exhausting" but rewarding, despite the Labor party "not getting the result it had been hoping for".

"We've had a five week hurricane," he said.

"It was a lot of hard work and it was very intense.

"As a party we need to have a think about how we win back the voters who used to vote Labor."

Liberal MP Roger Jaensch, whose last minute zoom in the polls saw him comfortably reelected above Mr Brooks and Mr Ellis, took a moment to send "a little cheerio" to the Hare-Clark political system.

"The Hare-Clark system paints a very very very rich and detailed picture of our region," he said.

"To watch the flows of individual votes ... ten here, 100 there ... there's a lot to learn about what messages people care about, what they're worried about."

Unsuccessful Liberal candidate Felix Ellis slipped into the room moments after the ceremony began. He confirmed after the speeches that he would be contesting the recount after Mr Brooks' resignation.

"We've got an interesting couple of weeks ahead of us waiting for more counts and recounts, " he said.

"Whatever happens ... the Tasmanian people will have their say," he said.

"I'm looking forward to nominating for the recount."
