For the cheap, and not-so-lazy…
If you walk 1.5km from Sydney Airport Domestic Terminal to Mascot (train) Station(google.com.au) you can catch the same train for $3.80 instead of the original $16.40 that Airport Link want.
So, effectively you are getting paid $8.40 per kilometre walking.
Not exactly a deal I would say
