I'll be in Sydney for the first time (apart from an airport transit) for a few days in early March and looking for some pointers to make the most of it.

I'll be arriving from BKK with EK (sadly that flight stops a few months later) and hope to upgrade and use their chauffeur drive service in to town from the airport. Unfortunately, EK recently announced chauffeur drive would not be available on upgrades so unless I get availability early enough I'll need to make my own arrangements.

I've read about the Opal Card and the airport charge, but also a potential method to avoid it. What are opinions on the best way to get in to the CBD from the airport?

Regarding hotels, I've been told that staying centrally is best to give quick access to the touristy stuff I'll likely be doing, especially considering my time will be limited. I'm only there for a couple of nights and don't mind paying the going rate for a good hotel, but I'm Scottish so always like a bargain. Any recommendations, hidden gems, areas to avoid or other ideas?

I was looking at Super Rugby fixtures but as I'm there midweek look like I'll miss them. Any lower leagues or other sporting options on 5th or 6th March?

Returning to the airport I'll be in the same position as arriving regarding chauffeur drive (probably even less likely to get it considering it's a few days later again) so best options to get there for a 21:45 flight?

Thanks for reading.
