Williams have confirmed that Valtteri Bottas has stepped up his efforts to be fit for the Malaysian GP, but he will need clearance from the FIA to take part.
The Finn was forced to watch the season opener at Albert Park from the sidelines as the FIA medical delegate deemed him unfit to race after he picked up a back injury during qualifying on the Saturday.
The 25-year-old has just over a week to prove he can race again, and Williams deputy team principal Claire Williams says the team are doing everything they can to help him to regain full fitness.
"We are fully supportive of Valtteri and his determination to return to the cockpit in Malaysia," she told Autosport.
"He is receiving the best possible care and is doing everything he can to be fully fit again.
"We are committed to doing what we can to help the process, as of course we really want to see him back racing again.
"As he was deemed unfit to race by the FIA in Australia he will need to receive final approval by the FIA medical team in Malaysia on Thursday."
With the Malaysian GP taking place on 29 March, Bottas has spent some time in Indonesia to prepare for the race.
"Valtteri flew on to Indonesia where he had always planned to be ahead of the Malaysian GP to help acclimatise to the hot and humid conditions whilst also adjusting to the timezone ahead of the race," said Williams.
"He has a leading physiotherapist with him who is working with Valtteri and his trainer to make sure he gets the best treatment possible."
