A few months ago after searching on google maps to see how I could reach that spot, I parked the car nearby and walked a narrow track behind the golf course until I reached the boxes.
Both boxes were painted on all 4 sides, but one of them was behind a wired fence, so not easy to photograph, and with the Swan river just across from the freeway the sea motives and birds were just right.
Not sure who the artist is, it looks a bit like Amok Island's style, but I've been unable to find anything on these murals.
