Surfing in Sydney

Hi,
I'm wondering, do you guys need to wear wetsuits when surfing in the summer in Sydney? How about in the fall? I heard the water might still be cold even in summer?
How about sharks? Are there plenty of them? I'm thinking about going to Bondi. I'm from the Philippines, so I surf all year long wearing boardies only.
I'm planning to visit a friend in Sydney maybe next year.
Any tip would be appreciated. Thanks.
