I realise that no names database on the web recognises this but there is no such thing as an Aboriginal name, per se. The Australian Aboriginal people were more diverse in language and customs than Europe, speaking hundreds of different languages (not just dialects, but actual languages). The names that are called "Aboriginal" on the web are from a variety of different linguistic and cultural sources. From my research, Myee appears to come from a language in the Sydney area, but no-one knows for sure which one. The meaning may be correct however I would not take it as a definite fact.
