Gold Coast mayor says "all Australians" are connected to the ride at Dreamworld in one way or another.

In the wake of yesterday’s horrific Dreamworld accident that left two men and two women dead, Gold Coast Mayor Tom Tate has said the event was one of “the most emotional” tragedies the region has ever experienced.

Speaking to Today reporter Sylvia Jeffreys on Wednesday, Tate explained, “all Australians one way or another have connections to this ride, the theme park and the Gold Coast, and the community is feeling it.”

Tragedy struck the world renowned tourist attraction on Tuesday afternoon when four adults - 32-year-old Kate Goodchild, 35-year-old Luke Dorsett, 38-year-old Roozi Araghi and an unnamed 42-year-old woman - were killed on the Thunder River Rapids ride.

Goodchild's 12-year-old daughter and a 10-year-old son of the unnamed woman were also on the ride at the time.

"The irony here too," Jeffreys said, "is that it's one of the rides that's considered to be really tame and it's ridden by children as young as two. Your family's been on it, my family's been on it and it's not just of course the first responders who are really feeling this, but the staff here at Dreamworld too."

Tate agreed, saying staff are "used to giving fun and joy to people, and all of a sudden the memories... this memory will leave behind is the most horrific," adding, "The focus actually now is really how we can comfort the families of these people. The Gold Coast we will rally behind that... we'll get together and we'll do our best."

Tate also says the Queensland Premier's office has rushed to offer support in this time of need and reiterated that the major investigation now underway is imperative to ensuring the future prosperity of the tourist destination.

"It's essential to have the coroner's report findings and to ensure that this kind of incident doesn't happen again," Tate told Jeffreys, "and to build confidence back so that people know that's the reason why it happened. It's very important for us."
