Etihad will add more capacity on its Abu Dhabi-Melbourne route from 1 December.
The carrier will use Boeing 777-300ER on its daily service, offering 36 more seats than the Airbus A340-600 it will replace.
Etihad chief executive James Hogan says that the Melbourne route is one of the strongest performing in its network, and the additional seats will allow the carrier to increase its share of the corporate travel market.
Flightglobal’s FlightMaps Analytics shows that Etihad is the only operator on the route.
The airline has announced plans to increase its capacity to Australia over the next three years as it deepens its alliance with Virgin Australia.
Etihad, which previously held a 19.9% stake in Virgin, is also taking part in the airline’s recently announced capital raising which could see its stake rise to 22.2%.
