Ardent Leisure Pty Ltd failed to establish a risk management framework, resulting in the Dream World incident and subsequent penalties imposed by the ASX. The company's directors did not exercise due care and diligence, violating section 180 of the Corporations Act 2001. As a result, the company suffered financial losses, loss of goodwill, and decline in share value. To recover from this crisis, the company initiated a review process to ensure safety and established a risk management committee to mitigate future risks.
