Australia has 8 major international airports. Sydney Airport is the busiest of these, but you may find cheaper or more direct flights from:
Other airports around the country have the capacity for international flights, but either have limited options (such as Canberra Airport) or do not currently have any international routes (such as Avalon Airport and Newcastle Airport).
The best time to book flights from Australia depends on where you're travelling. As a general rule, domestic flights are cheapest 20-24 weeks (5-6 months) before you intend to fly. For international flights, there's more variation. Some destinations are cheapest 8-12 weeks before travel (New Zealand, Thailand and Singapore), others are 16-20 weeks before (Fiji, Japan and Korea) and a few, like Bali, are cheapest 24 weeks before take-off.

What are the cheapest international destinations from Australia?
Indonesia, more specifically Bali, tends to be the cheapest international destination from Australia. This is fuelled by the huge demand from Aussies for a laid-back holiday destination that offers beaches, resorts and a touch of the exotic. Everyday costs are cheap in Bali too, with meals and drinks costing just a couple of dollars.
The cheapest flights to Bali are available from Perth and Darwin.
Another gem in Southeast Asia, flights to Kuala Lumpur are among the cheapest options from Australia. KL is one of the area's biggest and busiest cities. The highlight is the Petronas Towers, but the gargantuan shopping malls, delicious local and fusion foods and the intrigue of the Batu Caves all have their appeal. KL is a great starting point for exploring Malaysia, whether you want to go to the Cameron Highlands, George Town or Malacca next.
The best prices are normally available from Perth, but flights to KL from Melbourne, the Gold Coast and Sydney aren't much more expensive.
Flights to Osaka Airport are among the cheapest international options from Australia, with direct flights from Cairns giving you the best price.
Osaka, 6 hours from Toyko and 1 hour from Kyoto, is one of Japan's most popular destinations. As well as the ancient temples, cherry blossom festival, tea shrines and incredible food, Osaka is popular for its Dotonbori district, Osaka Castle Park and its proximity to Universal Studios Japan.
