The huge numbers of Asian middle class who are attaining the wealth that allows them to travel , initially on low cost , will mean carriers like Air Asia are only going to increase over the next 20 years . Then you got the Chinese carriers all ramping up their plans for Australia . Not an option to ban them , Australia is only getting closer to Asia not further away ( 7 cm a year ) so it needs to be managed , putting in an ILS is a good idea in my opinion , planes fly ILS 's nicely . low cost base , huge networks with direct links in the future it's going to be interesting to see how Austrailan carriers respond . Not sure why Aust kids not learning mandarin in schools ?
