Unfortunately Perth will never really get any real size unless the swell is out of the W or NW.
So this "once in a decade swell" isn't really putting on a huge show in Perth.
However there are some nice fun waves around -
Here are some frame grabs from when i was shooting some 4K video this afternoon.
Too many reefs and Islands of shore to let it hit clean. The spots that get clean swell should provide some really good waves..Photos
Great Wave that one though
