We visit relatives in Newport Beach regularly and are spoilt because we can walk to and from the beach. This review is written as a visitor unable to be a 'freeloader' on relatives.
Sydney has so many nice beaches it's hard to differentiate. Newport Beach is a very nice beach but a bit unwelcoming to visitors. Traffic in the surrounding area is always congested. Facilities such as parks and toilets are showing their age, and parking seems solely reserved for residents. Even moving a couple of streets away from the beach is difficult, with everyone having the same idea, plus unconnected boat trailers/caravans taking up precious parking spaces. I prefer Sydney's southern beaches for less congestion and easier access. More
