Under-fire Ardent Leisure chief executive Deborah Thomas has made an emotional visit to Dreamworld for a private memorial to Tuesday's accident victims.
Ms Thomas, who came under scrutiny when she was granted an $843,000 bonus at the company's annual general meeting on Thursday, fought back tears as she led hundreds of Dreamworld staff to visit a floral tribute to the four people killed in this week's ride accident.
Ms Thomas was also criticised for not making direct contact with family members in the aftermath of the tragedy and on Friday apologised for any hurt the company's response may have caused.
On Thursday evening she pledged to donate part of her bonus to charity.
"I will be making a personal donation of $167,500, which comprises my entire cash bonus, to the Australian Red Cross via the Dreamworld memorial day event," she said.
A fund set up to help Dreamworld victim Kate Goodchild's daughters and partner has so far raised more than AU$24,000.
The Canberra mother-of-two died in her partner's arms after a ride accident at the Gold Coast theme park on Tuesday. Her brother Luke Dorsett, his partner Roozi Araghi, and Sydney woman Cindy Low were also killed.
Ms Goodchild's eldest daughter, 12, survived when she was flung clear of the ride, as did Ms Low's son, aged 10.
