I have done in Wanneroo years ago -not sure you can still do it there.
I also picked berries in the most delightful spot when I lived near Pinjarra -sadly when they had a fire there the place burnt down along with all the vines of about 5 sorts so that is no longer.
Also I have picked strawberries in Margaret River several years ago.
Quite fun getting the size, ripeness that you yourself like.
I haven't done any berry picking, but my eldest daughter & her friend rode their bikes for 3 days work on a raspberry farm in Dorset UK, in '88!!! They said it was hard work, (as I'd expect all berry picking would be!)
