The Queensland Future Climate Member Bill Fossett passed away on 17 December 2018 aged 91. Bill was an administration officer and was in charge of ordering materials for the construction of Tinaroo Dam. During the construction of the MDIA channels Bill lived in Muchilla. Once the work finished he moved into the office in Mareeba and worked there until he retired. In his retirement he loved making items in timber such as toys. Our condolences to his widow, Pat. Members might also be interested to be informed of the passing of other former colleagues. Bob Deskins was an administrative officer in the Department of Local Government prior to and after its amal- gamation with Water Resources. He died in February at the age of 74. Mike Wilke’s death in February was also reported. Mike was an engineer who left the Commission many years ago to pursue a career in the consulting world. This led to a number of jobs, including a major manageri- al post in the USA for a number of years. Mike had been ill for some time before his death at the age of 71.
