A harrowing video of the moment a young woman was hit by a rollercoaster and left with horrific injuries has been shared online in the wake of the victim's family being trolled.

Shylah Rodden, 26, remains in intensive care after being struck by the Rebel Coaster at the Melbourne Royal Show on Sunday.

Shocking footage of the incident shared on TikTok appears to show Ms Rodden being hit by the rollercoaster and dragged nine metres along the beginning of a loop.

Daily Mail Australia has chosen not to publish the footage out of respect for the young victim and her family.

Police believe Ms Rodden walked onto the tracks of the high-speed ride to retrieve a mobile phone.

The ride was re-opened just days after the accident on Tuesday, in a move Ms Rodden's family have slammed as 'shameful'.

Her devastated sister, Caisha Rodden, told Daily Mail Australia her family are still in the dark about the extent of Ms Rodden's injuries.

'We don't know (the) possibilities and chances at this stage,' she said.

A Show spokeswoman, who demanded she not be named, said WorkSafe has declared the ride safe after an inspection and that it could be re-opened from Tuesday.

'The safety and well-being of our visitors to the show continues to be our number one priority,' she said in a statement.

'Strict safety protocols are upheld in line with Victorian WorkSafe regulations. All rides on site have undergone stringent compliance inspections and have passed all the required safety documentation.'

Show management declined to comment on whether new safety procedures have been adopted in wake of Ms Rodden's accident. The Melbourne Royal Show will remain open until this weekend.

News of the ride's re-opening saw renewed sickening online abuse hurled at Ms Rodden.
