Qantas (www.qantas.com) is Australia's flag carrier airline and operates routes between Australia and the UK, USA, China, Japan, Thailand, South Africa, Philippines, New Zealand, Hong Kong, Chile, Singapore and Canada.
A large number of international airlines offer flights to Australia, including British Airways (www.ba.com) and Singapore Airlines (www.singaporeair.com).
The cheapest time of year to fly is generally in the window between the end of Easter and the beginning of July, which coincides with the onset of winter in Australia. Bear in mind that if travelling from Europe or the UK, your plane needs to stop somewhere en route – Singapore, Hong Kong, Taiwan, Japan and Dubai are all commonly used. Come March 2018, however, a new service from Qantas will allow passengers to fly from London to Australia non-stop.
Budget airlines such as Tigerair (www.tigerairways.com) offer flights to Australia from South East Asia.
