The ANZ-sponsored free wifi at Southern Cross Station is a nice idea, and would be quite useful… if it worked.
I tried for several minutes one day the other week to get it working, and couldn’t. My mobile could detect both an ANZ Wifi and a “Free public Wifi” network, but neither seemed to actually do anything.
Apparently it runs until the end of September, as well as (for some of this period) some cafes in Melbourne, Sydney, Brisbane, and Sydney Manly ferries.
I also spotted a tram the other day that allegedly has free wifi on board. Who knows if it actually works though.
