Time Out says
Take your surfy doggos to this friendly stretch of sand
This is the only dog-friendly beach in Sydney that directly faces the expanse of the ocean and not a bay or harbour. You’ll find it as you stroll along the Esplanade from Cronulla Beach out towards the headland of Kamay Botany Bay National Park. But to get that pupper access to the crashing waves, there are some drawbacks for dog owners. Off-leash canine visitors are only invited before 10am and after 4pm each day, and banned at other times (harsh) and there are no facilities for human bathers in the unpatrolled waters.
