And the figure is set to climb higher this week as hockey, swimming and athletics finalise numbers for the rescheduled Games.

Hawe will make her Olympic debut at the age of 33 having only earned selection to the senior Australian team at 29.

Victorian-born, she relocated to Tasmania where she rows for Huon and claimed gold medals at the 2017 and 2019 world championships.

The Australian Olympic Committee announced the 38-strong rowing team for Tokyo where it has qualified nine boats. Hawe is part of the women's sweep squad which will contest a pair, four and eight.

However, there was no place for Tamar's Ciona Wilson while Huon's Georgia Nesbitt had been unable to qualify a lightweight women's double scull at last month's final selection regatta in Switzerland.

Hawe joins Launceston road cyclist Richie Porte, Grove canoeist Daniel Watkins, Perth track cyclist Georgia Baker, Launceston triathlete Jake Birtwhistle and King Island runner Stewart McSweyn as Tasmanians on the Olympic team while Forth runner Deon Kenzie has been named for the Paralympics.

More Tasmanians are likely to join them when Australia's hockey squads are named on Monday with swimming and athletics next in line.

Other Tasmanians were on hand to lead the congratulations as Australian Chef de Mission Ian Chesterman, of Legana, Lindisfarne's Olympic champion Scott Brennan and Hobart's Rowing Australia chief executive Ian Robson welcomed the rowers to the team.

"Australia has such a rich Olympic legacy in rowing and these athletes should be very proud that they will continue to build on this outstanding tradition," Chesterman said.

"Today is also a great moment for the families, friends, supporters, coaches and support staff who have helped these athletes realise their Olympic dream in Tokyo."

Brennan, who won Tasmania's last Olympic gold medal in 2008, and his wife Kim presented athletes with their tickets to Tokyo at the Adelaide Oval.

Robson added: "The selection to the Australian Olympic team is a proud moment for all our athletes, it reflects their hard work, resilience and determination to succeed in our sport of rowing.

Launceston-born swimming world champion Ariarne Titmus edged closer to her first Olympic team on Sunday when she qualified fastest from the heats in the 400-metre freestyle.

Meanwhile in Prague, Watkins continued his build-up to Tokyo by progressing to the semi-finals in the men's C1 at the ICF world cup following a fifth place in Friday's heats.

The Games are scheduled to run between Friday, July 23, and Sunday, August 8.
