My nephew lives on the Sunshine Coast in Queensland, which has just been hit by Cyclone Oswald.
One of the amazimg natural phenomenoms associated with it is a huge amount of surf foam that has blown onto the highway that runs beside the beach.
Check this video out of foam across a 4 lane highway.....

Wow, that is crazy!!!

Wow! That's some car wash you have down there.

That is pretty insane!!  (Need some guys with squeegees out there to clean off people's windshields!)

lol.. now thats pretty wild. Haven't seen sea foam like that in some time.
