Before you get to these stairs, there is a really nice open park that your dog can have a run around in. If you continue up these stairs you get a nice view of the city and the Anzac bridge. It's also a nice walk for you, your kids and your dogs to walk through the quieter areas of Balmain.
This is a pretty easy cache to find and should only take about 5 minutes at most to find it. It's also my first hidden geocache so I hope you enjoy looking for it!
P.S. bring a pen if you want to sign the log book.
Also, make sure to put the log book back facing downwards so the staples are at the top, otherwise it makes it difficult to get it out and place it back where you found it after signing the log book or find the cache, :)
