I think there are two reasons for this.
The first is that I haven't been travelling around as much as usual - work generally takes me to a variety of places around Sydney, but that hasn't been the case of late.
The second is that Energy Australia, the RTA and Australia Post have done a pretty good job of cleaning up their assets in this area, and the graffiti simply hasn't come back yet. There is nothing worth reporting in the places that I've been visiting.
The exception of course is Telstra, who are utterly useless. I need a major motivational boost before I start chasing them again.
I read a letter to one of the newspapers this week from a reader that was upset that the RTA had not removed graffiti along a certain stretch of road. I haven't been able to find that letter online, and I can't remember which paper it appeared in. I was going to write back saying, "All you need to do is contact the RTA and ask them to remove it - writing a letter to the paper won't fix anything".
They did have a point though - the RTA regularly patrol our major roads, but they never bother to report and act on graffiti along the noise walls etc. That really annoys me.
