No more than Bondi. Its the northernmost of the Northern Beaches in Sydney ( real name Palm Beach) so there'll be the odd shark about.
Summer bay is Palm beach 40 minutes drive north of Sydney.very large beach with a outdoor swimming pool to the right.To the left is the actual cafe in the TV show .indoor scenes fimed inside a studio.
BTW, I'll be back off to Aus in a few months. If you're interested, there's a good chippy not far from the beach
