It's lag, mate. You see, we are so far behind the rest of the world that we are only just beginning to realise that with the hillsides, roadsides and darn near anything that moves (including the school walking buses) plastered in Hi Vis psuedo-safety BS, that anyone wearing such an ensemble is actually NOT noticed any more because they just blend in with the other fluro leemings choking our visual landscapes.
The more advanced and enlightened peeps in the Northern Hemisphere realised that ages ago and shelved the idea. Give us another 10 years and if we're lucky, the abominable visual pollution penny will drop here down under.
P.S. You rained out yet? What the heck happened to Summer? It was only 3 days long this year.
