We, my wife, my grandson and daughter will be traveling through Sidney on our way to NZ mid June 2020. Will stay in the city and looking for tips of things to see and do. Thanks for your input. MTG

Well, thanks anyway.

Taronga park zoo, Circular quay, restaurants, gunshops, Centrepoint (if that's what they call it), ride the monorail, opera house, Fort Denison, tour Sydney Harbour on a boat.............lot's of stuff to do in a city you've never been too.
