Yesterday the country's largest ISP, Telstra, started filtering all customers' connections for child pornography. The filter is DNS-based, meaning it's easy to circumvent, but you can't opt out of it — if you sign up to a plan with Telstra, your connection will be filtered for certain web addresses whether you like it or not. One giant step for censorship or only a positive move in the war against child pornography? Only time will tell.
