Niall Coburn led the ASIC complex investigation into Kleenmaid and its three directors, from 2009 to 2012 and with his ASIC team, prepared the Criminal Brief for the Commonwealth Director of Public Prosecutions (CDPP) in 2011. This complex investigation involved a review of the collapsed Kleenmaid Group who owed $100 million to creditors and discovery of four million financial and other documents and interviewing and taking statements from numerous witnesses.

The case is ground-breaking as it has seen a shadow director jailed for criminal insolvent trading. The investigation led to the imprisonment of Andrew Young for 9 years on 9 February 2020, the imprisonment of Bradley Young in December 2016 for 9 years and the imprisonment of Gary Armstrong who pleaded guilty in October 2015 and who received imprisonment for a period of 5 years 6 months.
