Sydney Airport

SYD · 26 monitored domestic routes · data from Jan 1985

Airport traffic: to Apr 2026

Sydney handled 3,517,115 passenger movements in Apr 2026, the 1st busiest of the 22 monitored airports. International services account for 39% of its traffic. Traffic has returned to roughly its 2019 level. Across its 18 monitored routes, 2.9% of flights were cancelled — above the national average.

A passenger movement is not the same as a passenger. Every domestic passenger is counted twice — once departing, once arriving — while an international passenger is counted once. That is the official definition, and it is why these totals cannot be added to the route figures elsewhere on this site.
