The victim was transported to the Royal Melbourne Hospital, where she was treated for critical injuries, according to a statement by the Melbourne Royal Show.
The statement, posted to Instagram, also confirmed that the ride in question, the Rebel Coaster, "will be closed for the foreseeable future, and updates will be made as information comes to hand."
"It's a very tight-knit show community … and everyone is totally devastated," Melbourne Royal chief executive, Brad Jenkins said on a radio broadcast.
"The show is about putting smiles on people's faces, and tragedies like this are just devastating for everyone involved."
Although the ride will stay shut, the Melbourne Royal Show, which is set to go on until Sunday, October 2, will remain open.

The victim's father, Alan Rodden, told Daily Mail that his daughter's injuries "are horrific."
"She's brain-damaged. It's pelvic, her arms, legs, back, neck — there's hardly a thing that's not broken," her dad continued.
A sense of mystery surrounds the incident, according to him. "There are a lot of stories going around and I don't know which one is true and if someone is covering their tracks," he said.
The report also suggests that Shylah was working at the park and went to help a friend out at a stall on the day of the incident.
During her break, she decided to go on a few rides with a coworker, which is when the accident occurred.
An anonymous onlooker, who claims that the victim fell from the ride, posted a short clip from the scene on TikTok.
"We're still traumatised, and our hearts are with her loved ones. We were a group of four standing in line for the escape room, which is next to the roller coaster," the TikToker posted.
"Three of us were facing and looking towards the roller coaster and watching the ride while chatting; suddenly, we saw the roller coaster stop," they continued.
"As this had occurred, we saw limbs in the air from the right side of the carriage, and then body fell and slammed onto the concrete in front of us. Her body was a few steps away from us with only a metal fence between us."
The passengers on the ride ended up remaining on the ride carriage for hours after the incident, according to aforementioned reports.
This isn't the first tragedy to strike the Rodden family this year.
A social media post from earlier this summer revealed that Shylah had also lost her older brother recently.
As of Monday, she remains in a coma. Local outlets reported that a vigil was conducted by her bedside as she fights 'for her life'.
