The Australian ringneck (Barnardius zonarius) is a parrot native to Australia. Except for extreme tropical and highland areas, the species has adapted to all conditions. Traditionally, two species were recognised in the genus Barnardius, the Port Lincoln parrot (Barnardius zonarius) and the mallee ringneck (Barnardius barnardi), but the two species readily interbred at the contact zone and are now considered one species.

The maroon shining parrot (Prosopeia tabuensis) or red shining-parrot is a species of parrot in the family Psittaculidae. It endemic to the islands of Vanua Levu and Taveuni in Fiji and was introduced to the islands of southern Tonga in prehistoric times.
