Kaylee McKeown returned to competition at the Swim GP after an illness-ravaged 2026.
Mollie O'Callaghan missed the event due to an infection.
Australia's Dolphins are tipped to star at the 2027 World Championships in Budapest.
Battered by illness and injury, a trio of Australian Olympic swimming stars are being backed to be ready for Los Angeles Games.
Between them, Kaylee McKeown, Mollie O'Callaghan and Kyle Chalmers have won 11 Olympic gold medals.
McKeown returned to competition over the weekend at the inaugural Swim GP in Melbourne, having not raced since last year because of glandular fever.
Chalmers was poolside at the event, in the midst of a six-week break from swimming as he manages long-term back problems.
O'Callaghan, who nursed back and shoulder injuries through the Glasgow Commonwealth Games, was a late withdrawal from the Swim GP because of a skin infection.
McKeown said the one positive of her illness was that it had happened this year, not next.
Australian swimming head coach Rohan Taylor echoed that sentiment about the three stars in the context of the four-year Olympic cycle.
"No-one will remember what happens in 2026 [in terms of injury or illness]. You can't worry about that now," Taylor told AAP.
"You have to get them right, you have to remember their talent won't go anywhere.
