Hugo Fauquenoi: Great surfing spot for beginners, although I would recommend Manly Beach and its regular waves. Gets crowded in summer but is definitely a place to be 30mn from the City. Bondi to Coogee is a must do
Lenka Racanova: Love this beach. Small & hidden. Make sure you bring your food as the kiosk gets busy at lunch & they constantly run out of things...and also the food is a rip of.
Cristiani Graebin: Good for families. The playground is completely fenced and kids enjoy a lot playing on the sand. The swimming pool is perfect for families, as it suits swimmers and kids.
