Canberra BMX star Caroline Buchanan is in "good spirits" and "moving in a positive direction" after her crash on Saturday.
Cycling Australia said the eight-time world champion was expected to make a full recovery despite spending three days in intensive care over New Year's Eve.
It's believed she was riding a quad bike on a private property near Cooma when it rolled, causing extensive injuries that included a broken sternum, broken nose and collapsed lungs.
An ambulance later transported her from Cooma Hospital to Canberra Hospital on Saturday night.
Buchanan's now recovering in a private room having spent New Year's Eve in the intensive care unit.
She shared graphic images of her injuries on Instagram on Tuesday night after she was moved to a private room.
Buchanan will continue to use her social media accounts to keep fans updated about her progress.
Cycling Australia released a statement about the 27-year-old on Wednesday.
"Cycling Australia has confirmed that Australian BMX athlete Caroline Buchanan is progressing well following a vehicle roll-over on Saturday, December 30," the statement said.
"Buchanan was with a friend in an off-road vehicle on private property outside Canberra when the accident happened on Saturday afternoon.
"The family has confirmed that Caroline is in good spirits and that everything has been moving in a positive direction since confirmation of her injuries (broken sternum, broken nose and collapsed lungs).
"She is expected to make a full recovery and will keep fans updated on her progress via her social media channels."
While BMX isn't an event at the upcoming Commonwealth Games on the Gold Coast, the Australian national championships will be held in Western Australia in March.
The world champs will then be held in Azerbaijan in June. It's unclear whether Buchanan will be fit to ride at either event.
She finished second at last year's world titles and has won five of her world crowns in the discipline, with the other three coming in mountain biking.
