the bridge climb can be an amazing experience but it's very
expensive and u get a cert end of the climb.

try the seafood restaurants at darlington wharf and shop the
weekend paddington market (sat only from 10am till 4pm). also visit
chinatown and skip the char kway teow and laksa. visit bondi beach
for one of the coolest beaches around. sydney aquarium also a cool
place.
for the country side, visit the scenic blue mountains, west of
sydney. there are connecting train from the city to blue mountain
but the best experience would be to drive up. car rental easily
available there if not u can always join those day tours provided
by the local agencies.
up north if u are a wine lover, be sure to visit hunter valley
which housed some of the finest aus wineries. u can savour wine and
enjoy the scenic view. there's also hot air balloon travel over the
wineries but it's much more expensive than the bridge climb.
cheaper hot air balloon travel is at cairns. there's also a cheese
factory in the area and u could visit and see how cheese are
made.
the other country side would be port stephens. a very beautiful bay
with beach resorts, nice beaches and it is home of the bottlenose
dolphins where u can stand in the waters, get close to the dolphins
and feed them.
