We enjoyed the best coast holiday we've had as a family at Mollymook last March.
We stayed in the quintessential beach house - which was worth every penny as it was perfectly suited to a family and child friendly (would not be so good for toddlers but was perfect for kids aged 5, 6, 7 ...).
We hit Mollymook in Autumn, but when it was still warm enough (just) to swim but not too hot to be uncomfortable. The kids couldn't get enough of the water and the rest of us couldn't get enough of walking along the sand. We enjoyed the weekend markets at Mollymook Beach, and the pizzas in Ulladulla, but most of all we enjoyed buying our own oysters and prawns and eating them the old fashioned way with salt, pepper, lemon, alongside a fine NZ sauvignon blanc.
