An Australian father is in a coma in Bali after a horrific motorbike accident left him with bleeding on the brain and internal injuries on Saturday.

Erran Braddick of Gladstone, Queensland, flew to Bali on Friday for a holiday with his girlfriend but had been there just one day when the accident happened.

Details of the crash are not yet known, but the 32-year-old construction worker was rushed to BIMC Hospital, Kuta, where he remained in a coma on Monday evening recovering from multiple surgeries to save his life.

Mr Braddick's sister Daneile said both his lungs had been punctured and collapsed after multiple ribs were broken.

He suffered lacerations to his spleen and liver, along with bleeding on the brain where he has developed a blood clot, she said.

Daniele said Mr Braddick's girlfriend had not been on the bike, which had enabled her to keep a vigil by his side until his mother was able to fly in to Bali.

His nine-year-old daughter Bella does not yet know what has happened to her father, and the family is desperately hoping his condition will improve before they have to tell her what has happened.

'He's a wonderful father,' Daneile said.

'He's a strong person, he's a survivor.'

Erran's sister Daneile has been organising help in Australia, and set up a Go Fund Me fundraising page so as to raise the money to fly Erran home for medical treatment

Daniele has been organising help in Australia to fly her brother back for advanced medical treatment as the family cannot find any details of travel insurance and the cost of repatriation alone could climb to $130,000.

'The more I do, the less I think about what's happening,' she said.

Daniele has set up a Go Fund Me page which has raised more than $20,000 towards its goal in just one day as friends rallied to help the stricken family.

'Our goal is to get him back onto Australian soil as costs of him to remain at a hospital in Kuta are astronomical,' Daneile wrote on the fundraiser.

Daneile said she was grateful for the love and support of all the friends and family who had come forward with love and support.

'He just loves people. Everyone is reaching out to help us as he's the kind of guy that would help everyone else,' she said.

More than 170 friends and family contributed to the fundraiser within one day, adding their heart-felt tributes to their friend.

'Erran is a great bloke, I hope we can get him home and on the road to recovery soon,' wrote Ben Cash.

'Erran is a beautiful soul. Hoping for a full recovery and him to be home soon. Love Holly and Riley,' wrote Holly Meadows.

The fun-loving dad has an Instagram account packed with adventures including fishing, snowboarding, walking a tiger on a leash in Thailand, and hiking in Hawaii.

'He loves to travel,' Daneile said.

Further operations may be necessary and it is not yet known when he may be fit to fly.

Mr Braddick remained in a coma on Monday evening after surgeries to remove fluid from both of his lungs.

'His condition is now quite stable,' his treating nurse Zake told Daily Mail Australia by telephone from Bali.

Zake, who like many Indonesians uses only one name, said it was too soon to know what the prognosis would be.

'We need to wait for our neurosurgeon to evaluate him after surgery.'

The Department of Foreign Affairs and Trade (DFAT) told Daily Mail Australia that it is providing consular assistance 'in accordance with the Consular Services Charter, to an Australian man hospitalised in Bali and his family'.

'Owing to our privacy obligations we will not provide further comment,' the department responded via email.

While it is known that DFAT does not pay medical costs, the department would not say whether they would help with repatriation costs.
