Options for getting around Sydney for Tourism

We are 4 friends who are going to Sydney, Australia for 3 days from 31st December 2017 to January 3, 2018. We are going to Sydney for tourism purpose. So, for travelling within Sydney and nearby areas from Sydney, what is the best way to commute? Currently, we are planning something like below to cover:-

31st December 2:00 PM - 8:00 PM - Sydney City Outing, Ferry to Manly Beach
31st December 8:30 PM - 12:30 AM - Sydney New Year Celebrations - Sydney Harbor Bridge https://en.wikipedia.org/wiki/Sydney_New_Year%27s_Eve
1st January - Blue Mountains
2nd January - Local Beaches
3rd January - Depart

What might we use to travel to each place? Since we are 4 people, I think Uber might also be good, but I am not sure. The Blue Mountains are a little far away, what are the options there?

None of us wants to drive in Australia.

Sydney is reasonably well covered by public transport, with a combination of trains and buses. The buses aren't that easy to navigate so you should prepare your itinerary in advance or rely on a smartphone with a data connection or an offline app (no idea about those).

Get an Opal card; see Wikivoyage for some tips on using it. There's an automatic daily cap (like the Oyster card in London) so you don't need to think about passes in advance. You should however try to figure out how much you'll spend in advance since Opal is prepaid and it's practically impossible to get a refund as a foreigner.

A taxi costs $2/km plus fixed fees. Even for 4 people, public transport fares come out cheaper for anything but short rides. For example a peak hour train trip for 4 costs a little under $14 for up to 10km ($10 off peak), which is about the same as a 5km taxi ride. Uber is a little cheaper but not that much. There's a hefty supplement for trains to and from the airport, so there a taxi or Uber for 4 could be significantly cheaper (taking a local bus and possibly switching to a train may be even cheaper, but it would be slower and more cumbersome especially with luggage).

For the Blue Mountains, take the train. The stops on the the Blue Mountains line around Katoomba are good place to start exploring: they are little towns surrounded by nature. Keep in mind that unlike most mountains, people live tend to live on the crest, not in the valley, so a hiking trip ends with an uphill stretch.

On the 31st, which is a Sunday, keep in mind that the beaches (and the ferries to the beaches) and the approach to the New Year celebrations are likely to be very crowded. Expect delays as you have to queue for a ferry, bus or train, and be in the Harbour Bridge area early enough if you want a good view.

As for the beaches, Bondi, Cronulla, and the Wollongong area to the south are served by trains. For Manly there's a ferry from Circular Quay. Other beaches can typically be reached by bus, possibly from a train station further inland.
