Charges have been brought after four people died in a a horrific theme park accident.
Cindy Low, Kate Goodchild, Luke Dorsett and Roozi Araghi were all killed on the Thunder River Rapids ride at the Dreamworld resort on Australia's Gold Coast, in October 2016.
The four victims all suffered fatal injuries after the river ride malfunctioned and caused a collision between two rafts.
The two men and two women, who included brother and sister Kate and Luke, his long-term partner Roozi and Sydney woman Cindy, died almost instantly when the rafts collided then flipped onto the mechanical ramp of the River Rapids Ride.
Two tots – believed to be a victim's daughters, were thrown clear of the ride and survived.
Ardent Leisure, Dreamworld's parent company, on Tuesday announced to its shareholders that a prosecutor in Australia's Queensland state filed three charges against it over the deaths.
The company said the families of the victims had their "deepest sympathies" and said sorry to "all of the people impacted by this tragedy."
Charges have been filed after the accident was referred to a prosecutor earlier this year
by a coroner who said the Dreamworld theme park owner ignored warnings and failed to make adequate safety checks.
According to Reuters, all of the charges come under the Work Health and Safety Act 2011 and carry a maximum penalty of A$4.5 million ($3.16million).
Ardent said today that Dreamworld had taken steps to improve safety at the park.
An earlier coronial inquest this year stated the deaths at the Australian theme park were avoidable, reports Financial Review.
In a statement released by Ardent Leisure Group Limited, the company announced the charges to its shareholders.
It read: "Ardent Leisure Group Limited (ASX:ALG)(Ardent) acknowledges that the Queensland Work Health and Safety Prosecutor has today filed in the Brisbane Magistrates Court three (3) charges against Ardent’s subsidiary company, Ardent Leisure Limited (the operator of Dreamworld), arising from the Thunder River Rapids Ride tragedy in 2016.
"First and foremost, we again express our deepest sympathies to the families and friends of Roozbeh Araghi, Luke Dorsett, Kate Goodchild and Cindy Low for their loss and ongoing suffering and say sorry to all of the people impacted by this tragedy.
"There has been considerable change at Dreamworld over the last few years as was acknowledged by the Coroner in his Report.
"Dreamworld has taken substantive and proactive steps to improve safety across the entire park and continues to enhance existing systems and practices, as well as adopt new ones, as we develop and implement our safety case in accordance with the Queensland Government’s new major amusement park safety regulations."
