Hi Poz,
Firstly, the date 1928 definitely tells you it isn't from an Anson; the first one flew in 1936, although Ansons were fitted with Fairey Reed metal propellers of this type. The engine type "Cirrus II" is a good start, but Fairey Reed was the manufacturer of the propeller, not necessarily the aeroplane it was fitted to. The Cirrus II was an 85 hp four cylinder upright engine and was fitted to the following types, Avro Avian, de Havilland DH.60 Cirrus Moth, DH.71 Tiger Moth racer, Short Mussel float plane and Westland Widgeon. Of this lot, it's most likely to be the DH.60 Moth - if I was to guess, due to the number of these built and exported - it also ties in with the date. It's also possible that it is from either an Avian or a Widgeon, examples of both of which went to Australia. Bert Hinkler's Avro Avian that survives in the museum in downtown Brisbane is fitted with a Fairey Reed metal propeller. I hope this is helpful to you - and season's greetings to you and your propeller!
