Para 24 of “Prescription of aircraft and ratings — CASR Part 61 (Edition 1)” dated 23 December 2014 reads “Aircraft types for which flight training and flight review are required for exercise of privileges of a class rating — single-engine aeroplanes For regulation 61.062 of CASR 1998, each single-engine aeroplane model mentioned in a cell of column 2 of the table in Schedule 12, is a model for which flight training and a flight review are required under regulation 61.747 of CASR 1998 to exercise the privileges of the single-engine aeroplane class rating in the model”.
The Cessna 208 is listed in Schedule 12, so I suggest you draw your own conclusions!
