Christmas holidays abroad 2026 — travel eSIM guide for Australians

Christmas overseas is peak season for Australians abroad

The Australian Christmas and New Year holiday period — late December through January — is the busiest time for international travel. Europe in winter, Japan, South-East Asia, the USA — Australians scatter across the globe for the long summer break.

And whether you're at a Christmas market in Vienna or on a beach in Bali, you'll need data.

Plan ahead — don't rely on airport SIMs

Airport SIM card shops at international destinations are notoriously overpriced and often have long queues arriving at peak travel times. An eSIM purchased before you leave means you're connected the moment you land, without any fuss.

Popular Christmas destinations for Australians

Japan

Japan in December is magical — illuminations, snow in the mountains, and the famous New Year hatsumode temple visits. Mobile coverage is excellent throughout the country.

Europe

Christmas markets in Germany, Austria, France and the Czech Republic draw huge crowds of Australian tourists every year. A single Europe eSIM covers you across all of these countries.

Bali

For Australians who prefer warm weather Christmas, Bali is a perennial favourite. Coverage is strong in all tourist areas.

United States

New York at Christmas, skiing in Colorado, or Los Angeles for New Year — the USA is a popular choice. A Proost USA eSIM keeps you connected throughout.

Thailand

Koh Samui, Phuket and Bangkok are warm, affordable and well-connected over the Christmas break.

Tips for Christmas travel

Don't get caught with a roaming bill in the New Year

Australian carrier roaming charges can run into hundreds of dollars over a three-week Christmas trip. Sort your eSIM before you go and know exactly what your data will cost.
