I can't see CASA facilitating, assisting or promoting innovation in aviation design and development in Australia. CASA has always maintained the bland philosophy that the Civil Aviation Act directs them to be solely a regulator, with no mandate to promote aviation in any manner, contrary to the FAA's obligations.
Any regulator will impose maximum regulation to achieve it's aim. Designing and building new aircraft types in Australia would only complicate and compromise their regulatory function.
In my almost 50 years involvement in aviation, there has never been a darker hour for aviation in Australia.
