Australian holidaymakers looking to nab a good flight deal should generally look at departing within the first two weeks of December this year, according to Compare the Market research.
Ahead of another peak holiday season, the travel insurance comparison experts found flying earlier is generally better in December – with price differences in the hundreds, if not thousands, by not shopping around for flights on the same day.
Aussie travellers could score direct services from as low as $53 (Sydney to Melbourne) or spend more than $2,500 (Melbourne to Adelaide) per person one-way based on the flights studied.
Quoted flight ticket prices generally peaked in the week of Christmas, before settling down towards the start of the new year.
The price of one-way direct flights each day were quoted between 1 December 2025 and 1 January 2026 across Brisbane, Sydney and Melbourne to eight key destinations.

Compared to 2024 and 2023, the cheapest flights on average in December mostly remained steady this year.
However, flights from Brisbane to Hobart and Perth, Sydney to Hobart, Adelaide and Cairns, and Melbourne to Sydney, Hobart, Adelaide, Perth and Cairns experienced ticket increases on average year-on-year.
Compare the Market’s travel expert Catriona Rowntree said the findings highlighted that there were still ways to travel on a budget this holiday period.
“Travelling in the Christmas and New Year peak can be more expensive, but choosing to fly earlier rather than later in December generally means you could score a better deal on a ticket,” Ms Rowntree said.
“For example, the cheapest flights from Sydney to Cairns is $104 in the first seven days of December or $455 on the 27th of December just as the holidays start. That’s a shocking 77% difference!
“If you’re set on a date, Compare the Market found notable ticket price differences for flights on the same day depending on the time of day and airline. That’s why it’s really worth shopping around.
“Airports are stressful at this time of the year. Remember that to be early is to be on time, to be on time is to be late, and to be late is ‘holy cow we’ve missed the plane’.
“Anything from cancelled flights to lost luggage are likely, too. That’s why it’s really important to have travel insurance before you head on any domestic or international holiday.”
