Never got to take my sabbatical back in 2020 for the Olympics (thanks COVID), so I'm trying to plan something now for end of this year (Nov/Dec) to Australia/New Zealand. High level plan is to go US to Sydney, spend a few days there and then go up to Cairns for Great Barrier Reef stuff, then fly from Cairns to Auckland and do north NZ stuff and then fly back to the US. Looking for any input on things to do and amount of time I should plan (minimum ish) at Sydney/Cairns/Auckland area. Will be with family and my then 3 yo daughter for context.
