the tragedy unfolded.

It is believed the group were on the Gold Coast for a holiday from the national capital.

Last night police and consular officials were working to notify relatives of one of the men.

Ms Goodchild was a doting mother, whose Facebook page was filled with photos of her happy family.

Mr Araghi and Mr Dorsett made legal history in the ACT two years ago, successfully challenging a stamp duty bill on a home they bought.

The horror accident happened just after 2pm on the Thunder River Rapids ride, which is a water-based raft ride using a conveyor belt.

A young girl howled hysterically as her mum and three friends lay dead on the ride in the first fatalities in the park’s 35-year history.

All four were pronounced dead at the scene inthe worst Australian theme park disaster since 1979, when seven people died in a fire on the Ghost Train at Luna Park in Sydney.

Thousands of people poured out in to the car park as Dreamworld went in to lockdown.

It is expected to remain closed for several days as forensic officers, ride engineers and safety officials try to determine just what went wrong.

The case has been referred to the State Coroner and will almost certainly become the subject of a coronial inquest.
