From what I was told by CASA, back in 2013, an RAA registered aircraft does NOT count as a "registered or recognised aeroplane", since it does not appear on Australia's register of registered aircraft.
So, you need to be careful on assuming 190 hours in an RAA aircraft. There is also a requirement to spend time in a "complex" aircraft (Minimum speed, retractable gear, constant speed prop).
And I think you will find most, if not all GA CPL instructors will require a whole swag of time in actual GA aircraft (172, 182, 210, Comanche, etc)
Things have changed (a bit) since 2013, but we were told that the relevant clause here, allowing up to 100 hours in RAA aircraft, is "Pilot in Command Flight Time", which doesn't specify that it needs to be a particular aircraft type.
