The bulk of the Australian Olympic cycling team are facing disrupted travel plans to get to the Tokyo Games.
The Australian track and BMX freestyle disciplines, plus BMX racer Saya Sakakibara, have been training in Brisbane and, between them, feature 17 of the 29 riders in the Games cycling team.
They are due to fly from Sydney to Tokyo on Saturday week.
However two scheduled Brisbane-Sydney flights next week have been cancelled because of Sydney's coronavirus outbreak.
Simon Jones, the cycling team's performance director, said their biggest challenge was proving to be getting to the start line in Tokyo.
He said they might try to travel to Sydney earlier than planned.
"Getting down to Sydney for our flight to Japan looks like a bit of a challenge at the moment, because of the Sydney lockdown," he said.
"This typifies the last 12-14 months, in terms of dealing with these unexpected challenges, which seem to come up quite regularly.
"They tend to resolve, but quite late.
"We're looking at plan Bs - we might have to charter down ... we're leveraging our network."
Mountain bikers Rebecca and Dan McConnell were due to arrive in Tokyo on Friday - the first Australian cyclists touch down for the Games.
As always, the cycling program is a major logistical challenge at the Olympics, with events on every day of competition across the five disciplines and at different venues.
"We're descending on Tokyo from all corners, really," Jones said.
He added the repeated border closures between Australian states had caused "havoc" with the cycling team's Games preparations.
"COVID hasn't really been the issue ... but I do understood, other people are suffering more than we are," he said.
Asked about the cycling team's expectations for Tokyo, Jones replied bluntly: "Turning up".
"This isn't the time for medals. To be honest, if we turn up, we've got a chance," he said.
""If we get on the start line after all this, with fit and healthy people, we'll be racing and we'll be in the frame.
"All our focus is creating a safe environment and getting to that start line, which I tell you what, will not be easy."
