At the tender age of 19, Duffy became the first rider in the modern era to retain the Silverdome title.

A year after winning from 120 metres, Duffy was equally dominant from 40m to hit the front at the bell and storm home in 2:02.77, ahead of Victorians Jensen Plowright and Godfrey Slattery.

"It's really special to go back-to-back in front of my home crowd," Duffy said.

"That was something I really wanted to do.

"I knew I was a good shot from 40m and with a lap and a half to go I went for it and held on for dear life."

The Launceston rider said he has been a regular spectator at the carnival over the years.

"I would have been pretty young when I first came here with my dad and under-17s would have been my first taking part.

"It always looked like fun and I thought I'd give it a go."

Duffy was delighted to double up on an honour role which includes Danny Clark, Matt Gilmore, Brett Aitken, Matthew Goss, Caleb Ewan and Sam Welsford.

"I have not had a look at the list but it's pretty special to be up there."

After a bumper 2019 in which he rode the Glasgow world cup and Oceania track championships, Duffy has road and track nationals on his 2020 schedule.

Stewart also made it look easy in the women's race as the Devonport rider also banked a $2000 winner's cheque.

Combining with Queensland's Kristina Clonan off scratch, Stewart made up the deficit with three laps remaining and cruised to victory in 2:15.45 with Clonan second and young Victorian Keeley Bennett third.

"I've never won Launnie and don't win that often at the carnivals so it was nice to be able to get my hands in the air for once," said the 23-year-old former junior world champion.

"It's nice to finally get one for myself and prove to all my friends and family that all the hard work is worth it.

"It's such a good feeling to feel good and strong and I'm looking forward to the rest of the week.

"Devonport is really special to me and where I've missed out a few times and Burnie is equal prize money this year which is also huge motivation so I want to get greedy and go for all of them."

Stewart has spent a year in Adelaide training with the Australian team including fellow Tasmanians Amy Cure and Georgia Baker preparing for next year's Olympic Games in Tokyo.

"I'm not sure where I'm sitting but I'm loving it and have a good future ahead," she added.

The 180-strong population of Winkleigh conquered the world again on Friday night as Amanda Beams retained her global woodchopping title at the Launceston Carnival.

The 48-year-old's rivalry with American Martha King cranked up another notch as the pair put on a chopping masterclass to the delight of a modest crowd at the Silverdome.

King turned first on the 275mm log before Beams found her rhythm and stormed home.

"It's very special to win this," she said.

"We work our hearts out and to win a world title is something they can't take away from you.

"Martha beat me in 2017 so to go back to back is awesome. She towelled me up earlier this year so tonight was my turn.

"I've been training all my life for this. The more women's chopping events we have the better we all get."

Beams, who was cheered on by husband Dale, said her next woodchopping commitment will be the Sydney Show at Easter.

In the cycling undercard, Devonport's multiple former junior world champion Macey Stewart set a parochial tone for the evening with a popular win in the women's 1000 metres.

The only scratch-marker in the final, Stewart stormed home from back to front in 1:18.80, just ahead of Queenslander Lilliana Mcclennan with Launceston's Lauren Perry slipstreaming Stewart off 25m to third.

Kristina Clonan hit back in the A-grade scratch race, holding off Stewart's challenge to win in 9:33.54 with another Queenslander, Alex Martin-Wallace, third.

Clonan also edged out Stewart in the A-grade points score despite both riders finishing on 13 points, the national teammates dominating the women's events across the evening.

Victoria's Godfrey Slattery won the men's A-grade points score by two points from Reuben Webster, of New Zealand, and Stephen Hall, of Western Australia.

Queenslander Brandon Hutton claimed the 1000m from 55m in 53.16 just ahead of Burnie's Lachlan Spurr (80m).

Aside from one big tumble in the men's C-grade scratch race, the evening was largely devoid of crashes until the men's A-grade scratch race.

Japanese rider Minori Shimmura came down on the penultimate lap before limping off the track holding his shoulder as Hall stayed upright to take the win.

Hall came home in 16:32.83, ahead of Victorian Jensen Plowright with German visitor Moritz Augenstein third.

The series continues at Latrobe on Saturday before the two-night Devonport Carnival with Burnie making the seismic move from New Year's Day to New Year's Eve before Hobart (January 5) and St Helens (January 18).
