“Ms Sango was asked to provide an estimate of the reasonable costs of the two Australian defendants in the period up to, and including, filing of their defences. She has been a legal practitioner in Victoria since 1986 and a Law Institute of Victoria Accredited Specialist in Costs Law since October 2010. She has been engaged in numerous cases as an expert witness on costs in State and Federal jurisdictions, including group proceedings. I am satisfied she is qualified to provide an expert opinion on costs.”
