They give you a pass for the pylon, you can use the same day, another day or give to someone else. As we only had a few days in Sydney, we gave the passes to my Aunt to use with a friend.

Je ne vois pas la question !!!

Before you start the climb you have to practice climbing the ladders and stairs which are the same on the bridge, if she cannot do this (which is not demanding) they will decide if she can go. It is not difficult I have has a knee replacement and having the other one done soon and had no trouble, and it is more demanding on the knee than a shoulder

Ich würde nicht mit dem Auto fahren, sondern mit den öffentlichen Verkehrsmitteln (ist ganz einfach)

One day so what about climbing the pylon and walking over the bridge, get the ferry back, then take another ferry either to Watson’s or Manly and back for the views. Then walk to the opera house and back to Darling Harbour for the evening buskers. If you have time to pop in the free bits of the Sea museum that would be good, or pay to see the big ships. For the ferry rides you need to pick up an Opal card from any convenience store or tourist info place and you won’t need more than 16 dollars for the day as it has a daily max. Each ride is about 3-4 dollars. Daily max on sundays is less than 4 dollars meaning lots of free rides.

Hi 603queens The climb companies provide what you need for the climb - but I'm not sure if you get to keep their hat! If you Google Sydney Harbour Bridge Climb you can ask directly. Enjoy the climb!
