Many towns on the New South Wales coastline have long rock walls to stabilize their river mouth.
Some towns allow, or even encourage, people to use a rock as a canvas for a family memento...
Looks colourful. I have seen the breakwall at Port Macquarie and the paintings there look lovely. Our breakwater walls here haven't been painted though.
Interesting, especially because where I lived before there was a large outcropping that people used just like this. Then they put a road through and removed the rock. The removal created such a stink that the developer had to bring the rock back to a nearby location.
@casablanca Hi Casablanca - we're doing something a bit funny at the start of our trip - going South first, hence the Clarence River, down as far as the Hunter Valley (think wine!!) and then heading back up and away to the North. We had to visit our youngest in NSW before leaving for 5 months.. :)
