Dreamworld rapid ride tragedy: Brother and sister farewelled at Canberra funeral.

Two siblings who died during a tragic accident at Dreamworld on Queensland’s Gold Coast last month are being farewelled at a funeral in Canberra.

Luke Dorsett, 35 and his sister Kate Goodchild, 32, were killed when their raft on the Thunder River Rapids ride flipped on October 25.

On Monday morning, family, friends and colleagues gathered to pay their respects and say goodbye to the siblings, at St Christopher’s Cathedral at Forrest in Canberra’s inner-south.

The media were asked to remain outside during the service, which was to be followed by a burial at Gungahlin Cemetery.

Mr Dorsett’s partner, Roozbeh Araghi, and 42-year-old Cindy Low from the New South Wales Central coast also died in the accident.

Miraculously, Ms Goodchild’s daughter and Ms Low’s young son managed to escape without serious physical injury.

Ms Low’s family and friends said goodbye to her at a funeral on the Central Coast last Thursday.

Mr Araghi was also farewelled at a service in Sydney last week.

Dreamworld remains closed to the public, and is not expected to re-open until after the victims’ funerals.

It is still unclear what caused the accident. Queensland Police are investigating on behalf of the coroner.
