The Australian Open Access Support Group has compiled this page - http://aoasg.org.au/oawk-events-2013/ listing OAWk events. There will be events in every state and territory across the country and more than half the universities around the nation are celebrating the week in some manner (with more events to be added shortly).
Events range from competitions to win iPads or money to cover APCs, through to demonstrations, conferences, seminars and workshops.
Kerry, you will find on this page that there are HEAPS of things happening in Queensland.
