If the government stopped pussy footing around and built a dedicated fast rail link to Avalon it would be much more appealing for airlines and travellers.
Great in theory but in practice?? Airport rail links are an opportunity for extreme gouging through outrageous pricing!!
Brisbane Airport rail link to the City is around $30, or $10 more to go triple the distance to the Gold Coast. And whilst Brisbane Airport is only 50 minutes drive from the Gold Coast (in non peak periods), the train trip from Brisbane Airport to the Gold Coast takes over 1 hour 45 minutes.
I heard the Sydney Airport rail link is also outrageously priced!
