Australia's Sydney airport, the largest in the country, has proposed the largest terminal expansion this century to raise its capacity to accommodate a forecast increase in international air travel by 2045.
Transits will grow by 75pc to 72mn/yr in 2045, the airport said in a draft master plan, with 36.4mn international passengers/yr and 36.2mn domestic travellers/yr.
A major expansion joining the T2 and T3 terminals will be the biggest change to the facility since preparations for the Olympic games in 2000, Sydney Airport said on 15 September, a move that will increase capacity and enable more efficient runway use.
The airport had 41.4mn passengers in 2024, up by 5pc on the year but below the 44.4mn transits in 2019.
Domestic growth has been flat so far in 2025, with 12.12mn passengers recorded in Janaury-July, down from 12.13mn in the first half of 2024. But international transits of 8.27mn are 4pc higher than the year-earlier figure of 7.93mn for the same period.
International passengers will make up a larger share of total passenger numbers, the airport said, from 39pc of the total in 2024 to 50.4pc by 2045.
Meanwhile, air freight volumes will more than double to 1.4mn t/yr. This is despite competition from the new 24-hour Western Sydney airport at Badgerys Creek, 44km west of the central business district. The new airport is due to open in late 2026.
Australia's sales of jet fuel came in at 170,000 b/d in January-July, up by 7pc from 159,000 b/d in the same period a year earlier, Australian Petroleum Statistics data show.
