I'm travelling to Australia for a once in a lifetime trip with my 9 year old son to see U2 in Melbourne next March. We want to stay for 3 nights in Sydney but I'm not sure whether we should be in the City or by the beach. Having read a lot of the comments already posted, I'm tempted to go with Coogee, but can anyone give me any tips as to what I should do, bearing in mind I've got a 9 year old boy in tow who doesn't do shopping, but loves the beach! (He WILL get taken to the Opera House, though!).
