> The Government announced the filter two years ago as part of its

> ultimately it will make broadband more expensive in Australia."
> Google Australia support the Government's rollout of high-speed

> the internet is seen here."
> Geordie Guy from internet rights group Electronic Frontiers  
> Australia says the Government may well have to retest the filter on  
> the super-fast broadband speeds.
> "The filter hasn't been tested with speeds like the NBN proposes to

> critical mass.
> "We are probably starting to get around to the point where the  
> Government needs to go right back to the drawing board, beyond the  
> drawing board of a national technology response and see if this  
> really is the best way to protect children online."
