Where should I sleep after a 9 pm Sydney arrival before an early flight?

If the connection spans only one night, prioritise sleep and a reliable early taxi or walkable terminal access over city sightseeing.

Check whether you must change terminals, reclaim bags and recheck them. Set your hotel departure from the airline's check-in deadline.

Compare airport-area hotels by actual transfer hours and terminal served, not just distance. A shuttle that starts too late for your check-in is little help.
