What is the most expensive month to fly to Australia?

According to Qantas, the high (or peak) season, which runs from about the second week of December through January, is when airfare tends to be the priciest because of the heavy holiday-oriented traffic. This period is Australia's summer.



December is consistently the most expensive month to fly to Australia in 2026. This peak pricing is driven by a "triple threat" of travel demand: the arrival of the Australian summer, the Christmas and New Year holiday period, and the start of the primary school summer holidays for locals. During this time, flight prices from the Northern Hemisphere can double or even triple compared to the "shoulder" seasons. The weeks surrounding the Australian Open in late January also see significant price spikes. Conversely, the "low" season of June to August (the Australian winter) typically offers the most budget-friendly fares, though the weather is cooler and wetter in the southern cities like Melbourne and Sydney. For travelers in 2026 seeking a balance between good weather and reasonable prices, the months of October, November, and March are generally recommended as they offer pleasant spring or autumn temperatures without the exorbitant December premiums.
