An Australian man has died and a young mother-of-two has reportedly suffered life-changing injuries after a horror scooter crash in Bali. 

Bryce Alexander Black and Samantha Baillie, both 33, from the NSW Central Coast, were riding a scooter along Petitenget street in North Kuta when they crashed head-on with a car about 4.30am on Sunday. 

Mr Black died at the scene while Ms Baillie, his passenger, was rushed to hospital. 

Best friend Savannah-Leigh Homer said the young mother-of-two is currently in a critical condition and has set up a GoFundMe to cover the costs. 

The couple did not have travel insurance and Ms Baillie is now facing a bill of over $50,000. 

'She has suffered significant injuries throughout her body, including a fractured skull with bleeding on the brain, multiple broken fingers with severe hand injuries, injuries to her pelvis, and extensive injuries to her feet,' Ms Homer claimed. 

'She is badly injured and facing a long and uncertain recovery.'

Ms Homer said it was Ms Baillie's first time overseas and the couple had only arrived in Indonesia the day before the accident. 

She said the holiday 'was meant to be a happy milestone' as the young mum had 'recently starting a new chapter of her life'.

She said Ms Baillie, who works as a hairdresser, may not be able to work for a long time due to the severity of her injuries 'particularly to her hands'. 

Ms Homer said the family now need help as they face mounting costs, including the need to transfer Ms Baillie back to Australia and help support her with daily living expenses and rehabilitation while she recovers. 

'Sam's mum and I flew to Bali immediately and arrived [Monday] to be by her side,' Ms Homer said.

'We have already paid $6,000 toward her initial hospital care, and we have now been issued a further medical bill of $52,000, with more costs expected.' 

The fundraiser has raised more than $51,000 after it was launched on Tuesday. Donations have since been paused.

According to a Bali Police report obtained by Daily Mail, Mr Black died after suffering a severe head injury, bleeding from the ears, fracture to his left arm, and a laceration on his right leg.

Bali Police said the scooter had veered onto the opposite side of the road and was hit by a Honda Mobilio being driven by two Indonesian students.
