Flights to Australia are available for as cheap as $641 round-trip, almost half the typical airfare. Scott’s Cheap Flights reported that the discounted fares were available on trips to Brisbane, the Gold Coast, Melbourne, and Sydney, from either Los Angeles or San Francisco.

Though the ticket availability and prices vary depending on the route, seats are generally available for flights between April and July, and again from November through December — including peak summer season and Thanksgiving.

To take advantage of this flight deal, use Google Flights to identify the cheapest days to depart and return, and then book through an online travel agency like Priceline.

And if your search isn't finding you exactly what you want, Qantas is also selling discounted tickets to Australia, with fares starting at $899 round-trip. The 72-hour sale, which ends on March 1 at 11:59 p.m. PST, is valid for economy seats from Los Angeles to Sydney, Brisbane, and Melbourne.

Travelers can also book $949 round-trip flights from San Francisco, or $1,149 round-trips from New York City.

Qantas is also discoutning prices on premium economy and business class seats, meaning you can enjoy the long-haul flight in comfort starting at $2,149 round-trip. Travel dates for the Qantas flash sale vary depending on the route and fare class.
