Free Australia-Wide Wifi @ McDonald's Restaurants
209 stores across Australia currently have free WiFi, a further 500 more by March this year.
It's untimed, but a limit of 50mb per session does apply - so it would only really be of use for web-page browsing (not usable for streaming video etc.)
Even better, more and more stores are becoming 24hours -so logon anytime.
