A funeral will be held tomorrow for New Zealander Cindy Low, who was among four people killed by a ride malfunction at Dreamworld on the Gold Coast.
Ms Low and Australians Kate Goodchild, Luke Dorsett - Ms Goodchild's brother - and his partner Roozbeh Araghi died when their raft on the Thunder River Rapids Ride flipped over on Tuesday afternoon last week.
Their bodies were released to their families for burial on Monday following post-mortem examinations.
Ms Low will be farewelled in a private funeral tomorrow.
In a statement released this afternoon, her family said it would take a long time to find their way after the "catastrophic tragedy" that claimed Ms Low's life.
"We have spent every day trying to put one foot in front of the other, and it is extremely hard. It is impossible to imagine a world without Cindy, our beloved daughter, partner and mother to Kieran and Isla."
About 200 staff are back at work at the theme park, but the gates remain shut and police are still on site investigating the deaths.
Dreamworld has launched a parallel investigation, gathering evidence, as well as commissioning internal and independent safety reviews.
Investigators yesterday closed the air space around the park while they re-enacted the fatal incident using weighted dummies. The coroner was also present.
