Several rides and attractions will be open, while all slides, pools and cabanas will be operational at its adjoining theme park, WhiteWater World.

Dreamworld's reopening comes after the deaths of four visitors, Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozbeh Araghi.

They were killed on October 25 when two rafts collided on Thunder River Rapids ride near a large conveyor belt at the end of the ride.

Two children, who were also on the raft and witnessed their mothers' deaths, escaped without serious injury.

This afternoon, at a press conference outside Dreamworld its chief executive Craig Davidson said he expected the public to welcome the reopening.

"We have received tremendous support and feedback from the community and from our customer base around the park reopening and we are looking forward to seeing them all back next weekend," Mr Davidson said.

"We will be working hard with our team to show them a great time when they do."

Mr Davidson said "a number of Dreamworld attractions" would be fully operational from December 10, but could not give a timeframe for when the remainder of the rides would come online.

"That's not our priority. Our priority is to comply and work with the independent review," he said.

"Once we are all satisfied, confident in all of those safety aspects of those rides, we will start to operate them and that will be back online on an ongoing basis," he said.

"We are looking forward to next weekend. We have a very happy team at the park looking forward to getting back to work."

Mr Davidson said the families of those who died on the ride had been kept up to date about the reopening.

Money raised to go to victims' families

Mr Davidson said the opening weekend was being billed as "Open Hearts – Open Doors Charity Weekend".

"Furthermore $25 from every guest entry fee from the charity weekend will be donated to the Red Cross and Dreamworld will also contribute the $25 donation on behalf of all pre-paid ticket and passholders," Mr Davidson said.

"These funds will be distributed to those affected by the tragedy through the GIVIT Appeal independent distribution committee."

Mr Davidson also announced a six-month extension for all annual pass holders.

Dreamworld's parent company Ardent Leisure announced the reopening this morning via a statement to the ASX, in which the company said Dreamworld was "expected to incur approximately $1.6 million in one-off costs associated with the tragedy (net of expected insurance recoveries)".

"The closure of both Dreamworld and WhiteWater World throughout the month of November 2016 will result in no significant revenue being recorded for that month (2015: $7.6 million). In addition to lost revenue, the Theme Parks division is expected to incur operating costs in the range of $4.0 million to $4.2 million for the month," the statement said.

'Unprecedented safety review'

It was revealed last week that Workplace Health and Safety officers issued seven improvement notices to Dreamworld in the wake of the deadly ride malfunction.

The theme park acknowledged the breaches and said along with the improvement notices, several "prohibition" notices were issued concerning the BuzzSaw ride, specifying concerns with the "maintenance safety harness anchor points" and an error regarding the "maintenance safety chain".

Several of the notices related to Dreamworld's adjoining facility, WhiteWater World.

Earlier this month, Ardent Leisure announced the Thunder River Rapids ride would be demolished out of respect for the victims and their families.

Gold Coast Tourism Corporation chief executive Martin Winter said he had no concerns about safety at Dreamworld.

"I personally would definitely go back to Dreamworld — I am absolutely certain that all the checks and balances have been made," he said.

"I know that Dreamworld is a safe destination and I am certain that visitors to the Gold Coast will believe in that."

Dreamworld originally announced its intention to reopen on Friday October 28, just three days after the tragedy.

Park management said they wanted to hold a memorial service for the four people who died, then open smaller rides and other attractions.

But police expressed concerned about the plan, as Thunder River Rapids was still a crime scene.

Mr Davidson said reopened Dreamworld attractions would include the refurbished Tiger Island, the Corroboree Indigenous precinct, wildlife areas, the DreamWorks Experience, Wiggles World, ABCKids World and several motorsports precinct attractions.
