Queensland Police have finished their investigation of the crime scene at Dreamworld, almost two weeks after ride malfunctioned and killed four people.

The site has now handed the site back to Dreamworld, although police are continuing to investigate the incident ahead of a report being handed to the coroner.

Siblings Luke Dorsett and Kate Goodchild died alongside Mr Dorsett’s partner Roozi Araghi and another woman, Cindy Low, when their raft flipped on the Thunder River Rapids ride on October 25.

Following the tragedy, Dreamworld and its operators were criticised heavily for their response, including an attempt to re-open the park and some of its rides for a charity event just days after the incident.

Similarly, Dreamworld’s parent company Ardent Leisure was criticised for failing to contact the families of the victims sooner, and for failing to postpone its annual general meeting.
