Queensland Premier Annastacia Palaszczuk has vowed to ensure the Gold Coast recovers from the devastating Dreamworld accident that has left four dead.
"There will be a thorough investigation by the police and the coroner. We need to ensure that this never happens again," she told the Seven Network on Wednesday.
But she said the immediate priority was to ensure the children and family of the victims, staff at Dreamworld and emergency services who attended Tuesday's horror accident are cared for.
Brother and sister Luke Dorsett, 35, and Kate Goodchild, 32, and Mr Dorsett's partner Roozi Araghi, all from Canberra, and another woman died when their raft flipped on the Thunder River Rapids ride on Tuesday afternoon.
More counsellors and support staff will be sent to help staff and others deal with the aftermath of the fatal accident.
Gold Coast Mayor Tom Tate earlier told Nine that the council would help the family of Dreamworld.
"I mean, they're used to giving fun and joy to people and all of a sudden, the memories this memory will leave behind is the most horrific," Gold Coast Mayor Tom Tate told Nine on Wednesday.
"We're going to have to help the family of Dreamworld."
Ms Palaszczuk and Mr Tate said the accident had hit a lot of locals and Australians hard.
"Australians one way or another have connections to this ride, this theme park and the Gold Coast and everyone, the community is feeling it," Mr Tate said.
Both have vowed to ensure the tragedy is thoroughly investigated, but said the Gold Coast was safe.
"We will leave no stone unturned. There will be a thorough investigation by the police and the coroner. We need to ensure that this never happens again," Ms Palaszczuk said.
More than 30 police investigators are at Dreamworld again on Wednesday.
Mr Tate said the theme parks were vital to the Gold Coast economy.
"It's very important for us ... (to) help support the theme parks and get them back to the point where people have the confidence to come and live and have their wonderful memories again."
Ms Palaszczuk has urged anyone who needs help to contact Lifeline.
Lifeline on 13 11 14.
