An ISP, originating in Perth but now operating across Australia and NewZealand, who recently bought IHUG.
Their WebSite is http://www.iinet.net.au/
Their support pages include information for Macintosh and RedHat users.
BE WARNED: They have a habit of buying good ISP's and turning them into shit ones. They did this with an Australian ISP called !WebOne?, who went from really great local service to not having jobs and not keeping customers.
