How early can we drop off our baggage?

Hi, we are flying Qantas from bangkok to Sydney in the evening on Monday. We will be at the airport early that morning. How early can we drop of our baggage so we can go and relax in the lounge? We are flying business class, do we have access to any airlines business lounge?

Hi @Beautyfixx45
welcome!

The qantas website has most of this information.

You can use the Qantas recommended lounge
Louis Tavern

The other lounge that Qantas international business class passengers can often use is the
Cathay Pacific

If you believe this link Checkin will open at 1800 hrs for departures to Australia. However QF24 departs at 1810 so typically checkin will open 3 hrs prior to and closes 1hr prior to departure.
The alternative with bags is luggage storage at the airport but then you can't checkin

Just store the luggage and go into town for the day. With a bit of planning you can see some sights and be back at the airport having enjoyed the day before travelling all night.
