Domestic demand has been fairly flat for the last decade. 58-61m passengers domestically each year, and it hasn’t really moved since 2013.
2008-2013 the market had large gains with the introduction of Tiger Airways and Jetstar growing its local fleet, alongside the Virgin/Qantas capacity war.
Rex has likely picked up some of the Tiger share. Otherwise everyone is just talking traffic of each other. Remains to be seen where the numbers sit today and the coming years, obviously a whole heap of demand at the moment, will be interesting to see how far north of 60m passengers we currently sit at.
