SUP would be perfect in WA. Could do some long trips down the swan river or cruise around in the surf. Haven't been to Perth for a while but I reckon it would be popular.
It's huge over here.
I work on the river and there is a heap of people out every morning on them.
One of my mates, who is a truely awesome surfer from way back, just took his over to Bali to catch some waves.
One of his mates , who is a local surfer and photographer over there, made a video of him surfing, and it's unbelievable.
He's standing up in barrels on 10-15 foot waves.
Every one was in awe of what he was able to do on it.
