While much of the world is wrapped in winter coats, the Southern Hemisphere is heading into summer. That is what makes Australia and New Zealand in December such a good pairing: beaches, harbour fireworks and long outdoor days on one side of the Tasman Sea, pōhutukawa blossom and alpine walks on the other. It is also the start of peak season, so the trade-offs are real: heat waves in southern Australian cities, stinger-season warnings in the tropical north, rain on New Zealand’s wetter coasts, and crowds and higher prices as the school holidays begin. This guide covers five places to start with, how the two countries compare, the key events, and the planning points that matter most, including visas for Indian travellers.

Best of Australia and New Zealand in December

These five picks cover the range, from big-city summer to quiet coastline. Temperatures and crowd notes come from travel-planning sources and are averages, not forecasts.

1. Sydney: Harbour, Beaches and Fireworks

Sydney’s average December high is about 26°C, and the city is at its liveliest on New Year’s Eve. It is also where the Sydney to Hobart Yacht Race begins on Boxing Day, December 26, and the start can be watched from Sydney Harbour, where spectator cruises are listed. Southern Australian cities can also see heat waves above 40°C, so build in shade and swimming time, and keep indoor, air-conditioned stops in the plan.

2. Melbourne and the Great Ocean Road

Melbourne’s average December high is around 25°C, a little cooler than Sydney, though heat waves above 40°C are possible. One travel planner suggests a five-day Melbourne to Great Ocean Road self-drive as a summer itinerary. Roads and accommodation fill up around Christmas and New Year, so book early.

3. Tasmania: Summer Walking Without the Heat

Tasmania is the coolest part of Australia in December, with Hobart averaging a high of about 20°C. Much of the island is forested, mountainous national park, which makes it the pick for hiking. The same planner mentions bushfires in connection with Tasmania, so check local fire warnings before heading out on remote walks.

4. The Upper North Island: Beaches and Pōhutukawa

The upper North Island is New Zealand’s warmest and driest corner in early summer, with average highs of about 24 to 25°C. Northland, the Coromandel Peninsula and the top of the South Island are named as good for beaches and water sports. The pōhutukawa tree, nicknamed the New Zealand Christmas tree, flowers from November to January and peaks in mid to late December, covering the coastline in crimson. It grows naturally on the coast north of a line from New Plymouth to Gisborne, as well as around Rotorua’s lakes and in Abel Tasman National Park.

5. The South Island: Alpine Walks and Quieter Corners

December suits higher-altitude treks, and cooler temperatures make long walks comfortable, but snow is possible in the mountains and the weather is less reliable than in January and February. Dunedin, Queenstown, Invercargill and the West Coast get more rain in December than in any other month, so pack a raincoat. For fewer crowds, travel beyond the Bay of Islands to Stewart Island or the Catlins, which are cooler but at their warmest of the year. Book Department of Conservation huts on popular trails well in advance.

Summer in December: How the Two Countries Compare

Both countries are in the Southern Hemisphere, so summer in December is the season everywhere, but the experience differs. These are the main contrasts, drawn from travel-planning sources.

1. Heat: Sydney, Adelaide and Canberra average about 26°C in December, and Perth and Brisbane about 29°C, with heat waves above 40°C possible in several southern cities. New Zealand’s upper North Island averages 24 to 25°C and the South Island is a few degrees cooler.
2. Reliability: Most of Australia is dry in December, apart from the tropical north. New Zealand’s early summer is warm but less reliable than January and February, and the south and west are wetter.
3. Crowds: Australia is in high season everywhere except the tropical north, which is in low season. New Zealand’s peak season starts in December and builds through the month.
4. Beaches: Most Australian southern cities have good city beaches, except inland Canberra. In New Zealand, east coast beaches are suggested for swimming, and the west coast is wilder.

Tropical North Queensland in December: Think Twice

The tropical north is in its wet season in December. One operator describes hot, humid weather in the high 80s Fahrenheit (about 30°C), frequent downpours, occasional thunderstorms and sea temperatures around 29°C, while a planner puts temperatures near 35°C, with heavy rain making the water murkier and reducing visibility for snorkelling and diving. The Queensland Government says stinger season runs from November to May, when the risk from box jellyfish and Irukandji is higher. These are the precautions it and the Townsville City Council advise:

1. Swim only at patrolled beaches, between the red and yellow flags, and follow safety signs.
2. Use stinger nets where provided, but do not hang off them. Nets lower the risk and are not a complete barrier.
3. Consider a full-body lycra suit, often called a stinger suit.
4. If stung, call Triple Zero (000), pour vinegar on the sting and seek medical help, since Irukandji symptoms can take 20 to 40 minutes to appear.

There is an upside. Coral spawning can be seen on the northern Great Barrier Reef in November and December, and turtle nesting on the southern reef runs from November to March, according to one operator. If you would rather avoid the heat and the stingers, the southern states are a far easier December choice.

December Events and Holidays to Plan Around

1. Sydney to Hobart start, December 26, 2026: The Boxing Day date is Saturday, December 26, 2026, and the race can be watched from Sydney Harbour. A start time was not found, so check the race organiser.
2. Sydney New Year’s Eve, December 31: Sydney is especially lively. The Sydney Tower Eye lists 9pm and midnight sessions for December 31, 2026, though its page also promotes 2027 tickets. Public viewing areas have in past years used ballots and ticket releases months in advance, so check the City of Sydney’s official NYE site.
3. Cricket: Matches take place across Australia in December.
4. New Zealand holidays: December 25 and January 1 are nationwide holidays, and many attractions close at least on Christmas Day. New Year’s Eve brings big parties in small towns as well as cities.

Crowds, Bookings and Budget

Schools in both countries are out for several weeks over summer, and in New Zealand the break runs for about six weeks from mid to late December, with many workers off between Christmas and New Year. Accommodation, campsites, rental cars and transport cost more and sell out in advance. Expect the busiest roads in New Zealand, and drive with extra care. These are the habits that help most:

1. Book early: Popular New Zealand campsites can fill months ahead, especially over Christmas week, and the InterIslander ferry between Wellington and Picton sells out.
2. Choose the quieter pocket: Australia is large enough that quieter places are still available even in high season.
3. Fly into the outback: One planner suggests flying to Alice Springs or Uluru instead of driving in extreme heat. Alice Springs averages a December high of about 35°C.
4. Pack for both: Sun protection for Australia, and a raincoat and warm layer for New Zealand, even in summer.

Visas for Indian Travellers

Indian citizens need a visa for both countries. For Australia, a commercial guide from 2023 names the Visitor visa (subclass 600), with a base fee of AUD 150 and processing times that vary. That page is out of date, so use the Department of Home Affairs for the current fee and requirements. For New Zealand, a commercial April 2026 guide says Indian citizens need a full visitor visa, not the NZeTA, and lists an application fee of about NZD 300, an immigration levy of about NZD 41 and the NZD 100 International Visitor Levy, plus a visa application centre fee. Confirm every amount with Immigration New Zealand. Apply well before December, since processing times vary.

Season note: December is early summer in the Southern Hemisphere, so the season runs from the dry, warm south to the wet, humid tropical north in Australia, and from the sunny upper North Island to the rainier south and west in New Zealand. Late December is peak holiday time in both countries, so early December or the first days of January may suit anyone who wants fewer crowds.

Conclusion: Plan Early, Pack for Summer

The best of Australia and New Zealand in December comes down to choosing the right region: Sydney and the southern coast for beaches and fireworks, Tasmania and the South Island for walking, the upper North Island for warm water, and anywhere but the tropical north if you want to swim without stingers.
