There would be sites that contained data in the url but did not use standard authentication methods and thus the information was sent off shore to the usa. Once its in the usa, australias privacy laws no longer apply (and have already been breached, as customers were not made aware) and the us patriot act does apply, meaning that it can be used against australians. While this is not likely to affect regular users browsing the net on the phone it sets a very bad precedant and should not be taken lightly.
Then it might be worth highlighting to the paying opt-in customers of this filtering service that it can be easily bypassed using an offshore VPN service for a few dollars a month, a cost that wouldnt even put a dent in most kids pocket money.
