After an 18-month break from competition, Boedan Nelson makes his comeback to boxing at Saturday night's tournament in Penguin on Tasmania's north-west coast.

Nelson and clubmates Matt Hall, Kyle Marsh, Brad Morgan and Jake Pfeiffer will head across Bass Strait for the O'Callaghan Boxing Club classic.

All bouts will be three by two minute rounds.

In February, 2013, Nelson won the novice 57kg final at the Victorian Amateur Boxing Association championships.

He is unbeaten in three contests and won two by technical knockout.

In Penguin, Nelson will take on Aaron Bellchambers.

"It's my first trip outside Victoria," Nelson said during a break from training.

"A lot of my training has focused on endurance. I am really looking forward to the challenge of competing again," said the 19-year-old.

The lead-up for the squad has include many workouts with long-time trainer Pat Connolly at the California Gully-based gym.

Olympic boxer Lynden Hosking has also joined forces with the man who guided him to the top by helping out at BABC training sessions.

Marsh first took up boxing for fitness and goes to Tasmania having lost his first and second bouts on split decision and won his second on TKO.

He will fight in the 76kg division on the Penguin card.

"I've been putting in a lot of hard work," Marsh said of sparring and technical workouts in the gym.

"Being trained by Pat and Lynden has helped me a lot. They have a lot of experience to draw on."

Pfeiffer will make his competition debut in a 52kg bout in Penguin.

The 15-year-old said a lot of his focus in training was on defence and body shots.

After wins at Werribee, Morgan and Hall will be determined to box well in Tasmania.

Hosking said there was a lot of talent in the group.

"They all have a great attitude in terms of training and wanting to learn.

"It's great to be working together with Pat and helping these boxers be the best they can be."
