Right I'm starting to get organised for my HKG/SYD trip as is now a little over 2 weeks away 
As I'm over-nighting both ways in HKG I'm going to be using the Airport Express/MTR to get to my hotel in HKG. Using the same hotel in HKG for both stop-overs each way to/from SYD.
The hotel I've chosen in HKG is close to the Causeway Bay MTR station so I need to get on the Airport Express to Hong Kong station and then Central station to Causeway Bay station.
The only thing I can't work out is how to get from Hong Kong station to Central station [:?]
My other question, as I'll probably be buying one of those Airport Express Tourist Octopus cards, is can you buy these from the airport before getting on the Airport Express [:?]
Thanks and Regards
