If you have an outbound domestic flight on QF that day and you are OW-Emerald (there is no such thing as AA-Emerald) then you would have access to QF domestic lounges (including business lounge if available).

If you have an outbound international flight on QF or a OW airline (assuming such exist) then I suspect you still would not be able to access the domestic terminal.

If you are arriving on a QF domestic flight with no ongoing flight that day, QF lounge rules state no access. I travel several times a year on QF domestic flights as a OW-Emerald and always go the QF Business Lounges before outbound flights.
