"I do not think the deficiencies I have identified are ones that could only have occurred in the specific circumstances of the Home Insulation Program. Several systemic or fundamental shortcomings can be identified which not only are capable of repetition … but which might be avoided through
diligence and the taking of some additional measures.
I would recommend that the Australian Government use the experience of the Home Insulation Program as a means by which to learn from the mistakes identified in the report, many of which can be traced to overconfidence and unrealistic optimism." (2014) 
Ian Hanger AM QC was the Royal Commissioner who led the Royal Commission into the Home Insulation Program in 2014
