Lol. Should I have said "St Kilda is a controversial place to surf with a high volume of people, occasionally filthy water, and too many Europeans, most of whom are instructors who are dicks to everyone and use the beach for their own nefarious purposes."
Look, the truth is that it's close to the CBD, it's got a huge beach and flat water and no power lines to chuck your Cabrinha into. If it were an awful place to surf, no one would be there.
