So I am currently at the Ibis Sydney Thornleigh and WiFi access is chargeable at AU$10 (or AU$15 for premium) per 24 hours. Earlier this year, I purchased the Microsoft Work & Play Bundle for US$149 and it came with unlimited Skype WiFi access (amongst a ton of other things) - apparently this is the ONLY way you can get UNLIMITED Skype WiFi but I never thought much about it since WiFi is usually readily available.
