Due to the current Covid-19 pandemic, all regular services and hours may be subject to change. Thus, if the idea is to spend the night in the public area, consider a plan B in case the stay inside the airport is only allowed for those who are close to boarding.
Spending the night at the airport
Sydney airport closes for a few hours at night. However, if you have a ticket for the next morning the security staff will let you spend the night inside a waiting area situated in Terminal 1. Have some warm clothes prepared, as the place can get pretty cold.
Where to rest: Most seats inside the enclosure have armrests. In particular, the waiting area designated for layover passengers is poorly equipped and has very few benches. There are several VIP lounges inside the terminals if you want to enjoy more amenities. If you wish for a longer rest, there are a couple of hotels situated in front of the terminals.
Baggage: In Terminal 1 there is a left luggage service that operates from 6:00 am to 9:30 pm.
Eating and drinking: Inside the designated waiting area of Terminal 1 there is a vending machine.
Restrooms: Showers available in Terminal 1 and the VIP lounges.
Wi-Fi: No charge and unlimited.
The Rydges Sydney Airport Hotel is found across from Terminal 1, while the Mantra Hotel at Sydney Airport is located a few meters from terminals 2 and 3. Other options in the vicinity have shuttle services for their guests.
