The last time I tried it, it was $4.50 if you had a boarding pass. How many crew have one of them.
Wow. I was based in SYD and commuting to Mel until about Oct last year. I was renting a shoe box in Mascot and often caught the train to and from Mascot station and Domestic terminal. It was $5 but had to get the ticket at the window like you say.
I remember my holiday to the states last year. Flew into Ragan National Airport.,$2.90 for a train ticket into the city.
If you are Brisbane based the sky train is free from the city if in uniform.
Sydney blows.
