I will be in Sydney late December, I plan on spending a few days in Sydney, Bondi Beach and where else are good places to stay/sightsee ? I'll be staying at the hostels.
I'll only be in Oz for 6 days, so I don't think I'll be able to do any other cities, how far are they by bus and which nearest ones are have great attractions ? Perhaps I can do a day trip.
I've scoured the forum already but I can't seem to find an answer.
You can't 'daytrip' to another city in Australia. It's a BIG place. Your only option would be to get on a plane.
If I was only there for 6 days, I'd get out into Sydney harbour - it's huge but the ferries are great. You can visit Manly (good beach) and Taronga Zoo almost directly opposite the opera house.
I agree with steve who posted 4 days ago.
Forget any other cities do the harbour, maybe taronga park zoo, the sydney opera house, china town,darling harbour, and if you can I would take a day trip by bus, to the Blue mountains.
But check it out when you arrive the hostels are a great help, and can book everything for you with a slight discount.
