In Victoria ISP's who wish to provide an internet service to state schools must supply content filtering as part of the base package. At the moment there is a rather short list of Department of Education and Training approved ISP's who do this (and with some of these ISP's it is questionable how well they do it). Schools however do not "have to" use the filtering or the approved ISP's they can go outside VicOne (who supply the circuit) and the approved ISP's (who supply domain hosting, content filtering, upstream bandwidth etc.), if they chose. The Department has no mandate that will allow them to force the schools to use the services supplied, though after a recent departmental restructure they are looking at getting this changed. Even if schools use an "approved ISP" they can still turn the filtering off, as most of these ISP's have options for unfiltered user accounts, filtered accounts and accounts limited to the Edu-list. Edu-list is a collection of about 100,000 department approved educational friendly websites. So filtering has been around for a while in Victorian State Schools, just poorly implemented and while it is supposedly compulsory there are more loop holes than you can poke a stick at.
