"My son was beside himself": Mother shares terrifying Dreamworld experience on Rove and Sam.

A mother has shared her terrifying experience at Dreamworld when she and her three year-old-son visited the theme park only weeks ago.

Alicia told 2dayFM radio hosts Rove McManus and Sam Frost she took her son on the log ride because she “wanted something quite tame.”

The log ride is located in the same area as the Thunder River Rapids, where four adults were tragically killed on Tuesday.

The mother explained she was apprehensive about allowing her son to go on the ride but says she was assured by attending staff he would be safe so long as he made the height requirement.

“So we put him up against the measuring thing and he was a good 10-15cm taller and she said ‘oh, he’s fine’,” she said.

But Alicia said the ride that held its occupants in place with a metal bar soon revealed itself to be not as child-friendly as she first thought.

"There's no seatbelts, no safety harness, there's just a bar in front of you to hold on to and you press your feet against the floor to not fall out," she said.

"Inside it’s like a rollercoaster – it’s pitch black – and it drops you backwards quite suddenly and quite fast."

Alicia told hosts her son dissolved into a state of panic during this dropping phase, forcing her to physically restrain him.

"He was trying with all his might to climb out and claw me – he was really just you know, beside himself," she said.

"It took every ounce of strength and adrenaline to hold him into that log ride."

Rove weighed in with a reference to the 19-year-old who fell off the same log ride in April before expressing his own safety concerns.

“I guess one of the issues you do raise, Alicia, is when you talk about safety, is a lot of the people who are in charge of safety are just teenagers on their weekend job ... on barely minimum wage who just stand next to a big red button," he said.

The radio presenter then admitted he didn’t know what training was provided to those who attended the rides.

“It feels like you’re just an attendant, you’re probably taking tickets any other hour of the day,” he said.

Co-host Sam expressed her concern over whether staff were prepared for such an unexpected situation like Tuesday's disaster.

“You wouldn’t think that, you know, on a Tuesday, you’d be in the position where you have to be that alert, that you’d have to press the emergency button,“ she said.

Rove jumped back in to question what procedures were in place after the emergency stop is activated.

“Or when it happens, what are you trained to do, other than when you can hit the stop button and then what?”

The segment ended with all three participants continuing to question whether more could have been done to prevent the recent loss of life.
