The Olympian is facing an unknown route to the Tokyo Games as clouds continue to hover over international competitions and travel due to COVID-19.

Barber has four domestic meets scheduled leading into July's Olympics, but following next month's Australian Championships the 29-year-old has no idea what lies ahead.

Her coach and husband Mike Barber has a few scenarios in mind for the final push towards Tokyo, where the javelin thrower is one of Australia's best hopes for a gold medal.

"It's really still up in the air. We have the plan in place up to nationals, we'll take a few days off after that to reset and then I have no idea," Barber said.

"Mike has three or four plans in the works, it depends on where the world sits at that point in time.

"I'm very happy to be fluid this year and make the decisions as they come up, because it's about best preparing for performance in Tokyo."

MORE CANBERRA SPORT

Barber is steadily building towards Tokyo at the Australian Institute of Sport, with 2019 World Champion to fine tune her preparations at the Canberra Track Classic on Thursday night.

It's just her second meet since her Doha triumph, having launched her domestic season at the ACT Championships last month.

Barber threw 55.93 metres to comfortably see off South Canberra's Jess Bell (50.2 metres) and was disappointed by her overall performance, but said "there's still many more opportunities to show what I can do."

The athlete's personal best is 67.70 metres which was thrown at the Spitzen Leichtathletik meeting in Lucerne, July 2019.

"Honestly, it was weird [to be back]. That competition was more about just getting back into it," Barber said.

"It had been so long, there were some processes around competing that I really wanted to go through again before I came out in the actual domestic season to start throwing.

"It probably wasn't as hyped as I thought I might be, there were definitely a few things I was tinkering with so it didn't go to plan. I was disappointed about that.

"I wanted to come out guns blazing, but the reality was it didn't quite line up. I think it was a good chance to put myself through that again and just remember what it was like to immerse myself in competition.

"A few things to work on and technical things to tweak before the next competition. I'm feeling really good, so I'm looking forward to coming out [in Canberra] and really get the season started."

Barber was excited by the news that Brisbane had all but secured the 2032 Games a fortnight ago, when the International Olympic Committee confirmed it would enter detailed discussions its bid officials.

Like Barber was inspired by Sydney 2000 as an eight-year-old, she said the likelihood of Queensland hosting a future Olympics would do so again for a generation of young Australians.

"I remember Sydney being such a pivotal moment in my life knowing that being an athlete and competing in the Olympic Games is a possibility for me," Barber said.

"To hear it could potentially have the same impact on the younger generation is really exciting.

"Knowing there's a potential Olympics coming up, you could see a few more athletes staying in the sport, coming through and chasing that opportunity to compete at a home Games."
