Jo , You missed my point or perhaps I did not explain it better .
The Indigenous family's reliance on wild food plants as staples disappeared - they turned to protein .
If you were lucky there were fish and birds if you avoided the guns and poison and the Season was good - otherwise sheep and cattle would be the " Deadly Dividend " of white occupation .
The Land rapidly became putrid for Aboriginal People and in most settled parts of Australia remains so .

Yes, Loudmouth, how Aboriginal people lived and how they used the land was recognised in Australian law and still is, widely, extensively and unilaterally. How Aboriginal people lived and used the land according their own law was not, until Mabo. The comparison of traditional practices to the habits of native fauna comes when you try to infer Aboriginal law was recognised in Australian law prior to Mabo, it was not.
