In addition to Bondi and Manly, I am thinking fo taking a friend to one of the further out of town beaches.
Having lived in Sydney a few years back i know the distances and transport options etc, but am wondering which others might think would be the better, taking into consideration practicalities like the public transport, and what can be seen or done at the destination or any stops along the way. Other considerations like cost of fares and availability of food, either nice cafe or good take away to eat on the beach are helpful. One tends to associate (maybe wrongly) Nthn beaches with upmarket pricing.
Going via Manly at least one direction to Palm Beach is a bonus, but Manly on its own can happen regardless of which we choose.
