She is believed to have walked onto the rollercoaster tracks to retrieve her phone after it fell from her pocket, with eyewitnesses saying she appeared "fixated" by something on the ground.
Graphic footage of the incident was uploaded to TikTok, showing Rodden being dragged 9m into the air before plummeting to the ground.
NCA NewsWire has chosen not to publish the confronting vision.
The man who captured the vision said he was filming his sister and partner on the ride when he accidentally caught the tragic incident on camera.
"All of a sudden, I saw someone getting taken up but at the same time I'm thinking 'f***, my sister, my partner'," he told 7 News.
"But you can see she'd bent down to pick something up. I don't know if it was a phone or what, but she was so fixated on picking it up that she didn't even see the ride at all."
Authorities believe that Rodden may have snuck through the fenced-off area to retrieve her phone.
The Rebel Coaster reopened on Tuesday after WorkSafe finalised an inspection report and declared it safe to be reopened.
"It appears at this early stage the woman, believed aged in her 20s, may have walked on and entered the track to try to retrieve a dropped phone before she was hit by a rollercoaster carriage, about 5.45pm," a Victoria Police spokesperson said.
