I believe overloading the month field of CCYY-MM dates with new numeric values should be restricted to periods that cover complete Julian/Gregorian months or are strongly tied to them. Other seasons should use a different mechanism, probably a prefix letter.
Noongar seasons seem to be approximated by bimonths/sixth-years, starting with December. I have suggested systematic codes for those (and more) before, which would be: 20, 22, 24, 26, 28, 30.
