To contribute to what has been said from an airport worker’s perspective. Firstly, I wasn’t working at the airport when the biggest downpour happened as I was with the NSW Rural Fire Service (firefighter) responding to flood related firecalls all day up in the Northern districts however I’ve been told and seen that:
DOM 2 taxiway and ramp (T2 between Jetstar and Virgin Australian/REX B737s gates was flooded up to 15cm high.
The Jetstar/Virgin Australia bagroom (T2) was flooded up to 10cm high.
The Qantas bagroom (T3) was flooded (unknown height).
The airside road at the Qantas maintenance base (between maintenance 5 and 6) was completely flooded and thus unserviceable (unserviceable meaning unusable).
The international Swissport bagroom (serving Air NZ, AirAsia, American, Hawaiian and a few others) was flooded and thus unserviceable.
Runway 16R/34L was temporarily unserviceable due to flooding just North of the runway intersection.
That’s basically the important stuff covered. There was a lot more affected but doesn’t really impact the overall operations of the airport.
To have a better understanding, for each of the three terminals, passengers can only see/access about 1/5 of the terminal with the rest being underground staff operations area. As you could imagine, everything that’s underground got flooded.
