Hey D,
The scene hasn't changed much except for the crowds. Woodies is pretty nuts if you get there after work or on weekends. you can still get a sesh to yourself (pretty much) if you get there between 1 and 3.30pm. Weekends and pub hols are pretty crowded especially if you want the nice smooth stuff, but if you join in the circulation and don't mess up, it should be fine there's still a bit of room left.
Thieving is same as it ever was, plenty of scum bags at most beaches.
Most Metro beaches have plenty of kites now ALL flat water beaches are crowded including Woodies, Melville, Pinnaroo, Mullaloo and even leighton and Cottt get plenty of action.
Perth is a big place with lots of beaches and water. There are still loads of empty places to ride if you need space.
We are getting sea breezes already so it should bbe windy by the time you get back. Welcome home in advance!
Good winds,
