澳洲观鲸季节：东西海岸最佳观鲸地点与月份

Every year, roughly 35,000 humpback whales migrate along Australia’s coastline, making it one of the planet’s great wildlife spectacles. According to the Australian Marine Mammal Centre (2023), the east coast population alone has rebounded from fewer than 500 individuals in the 1960s to over 25,000 today — a conservation success story that puts on a show from May to November. On the west coast, the Western Australian Department of Biodiversity, Conservation and Attractions (2022) estimates a similar recovery, with 30,000–35,000 whales passing the Indian Ocean shores. We found that for most of us, the hardest part isn’t spotting a whale — it’s picking which side of the country to stand on. The east coast offers the classic postcard: breaching humpbacks against the Sydney skyline or the golden cliffs of Byron Bay. The west coast, meanwhile, delivers raw, empty beaches where you can watch a 40-tonne animal launch itself clear of the water with no one else around. Whether you’re chasing the first calf of the season or the last straggler heading back to Antarctica, the timing and location make all the difference.

The Great Migration: Why They Come and When They Leave

The humpback whales you’ll see off Australia are on a round trip of roughly 10,000 kilometres — the longest migration of any mammal on Earth. They leave their summer feeding grounds in the cold, krill-rich waters of Antarctica around April, heading north to the warm, protected bays of Queensland and Western Australia to breed and give birth. Calving season peaks between June and August [Great Barrier Reef Marine Park Authority, 2023]. After a few months of resting and nursing, the adults and their new calves begin the journey south again from September, feeding very little until they reach the Southern Ocean.

On the east coast, the northbound migration (May–July) tends to be more tightly packed because the whales are in a hurry to reach the breeding grounds. The southbound leg (September–November) is slower, with mothers and calves travelling at a more relaxed pace — meaning more time for you to watch them play. On the west coast, the timing is roughly the same but shifted earlier by a couple of weeks: northbound from late April to early August, southbound from September to December. The key difference is population density. The east coast stream is narrower and closer to shore, while the west coast migration spreads out across a wider continental shelf. Both are spectacular, but they feel very different.

East Coast Hotspots: Sydney to Hervey Bay

Sydney: The City Slicker’s Whale Deck

You don’t need a boat to see whales in Sydney. The Sydney Harbour National Park headlands — particularly North Head and South Head — offer land-based viewing that rivals any paid cruise. During peak season (June–July), you can spot 10–15 whales per hour from The Gap at Watsons Bay. The National Parks and Wildlife Service NSW (2023) runs free volunteer-guided whale-watching sessions at North Head from late May through October. If you prefer a boat, a two-hour cruise from Circular Quay will get you close enough to smell the whales’ breath (it’s fishy, but oddly charming). The best months for Sydney are June and July for northbound and September–October for southbound mothers with calves.

Byron Bay: The Hippie Whale Capital

Byron Bay’s Cape Byron Lighthouse is the easternmost point of mainland Australia, and it puts you right in the migration highway. The Byron Bay Whale Watching Committee (2022) recorded an average of 1,200 humpback sightings per season from the lighthouse lookout alone. The water is so clear here that on a calm day you can see the white patterns on the whales’ bellies from the cliff. The best time is June–July for northbound and September–October for southbound. If you’re lucky, you might spot a southern right whale — they’re rarer but hang around the bay for weeks at a time.

Hervey Bay: The Whale Nursery

Hervey Bay, about three hours north of Brisbane, is the only place in the world where humpback whales voluntarily stop migrating to rest and socialise. The Queensland Parks and Wildlife Service (2023) notes that the bay’s protected waters create a natural nursery, with mothers and calves spending up to a week here before continuing south. The season runs August to October, peaking in September. It’s the best spot for watching calves learn to breach — a clumsy, joyful spectacle that’s worth the drive.

West Coast Wonders: Exmouth to Albany

Exmouth and Ningaloo Reef: The Coral Coast Show

On the west coast, Exmouth is the undisputed heavyweight champion of whale watching. The Ningaloo Reef is one of the few places on Earth where you can swim with humpback whales — strictly regulated, but unforgettable. The Western Australian Department of Biodiversity, Conservation and Attractions (2022) reports that the Ningaloo region sees over 30,000 whales pass through each season. The best months are June to August for northbound, and September to October for southbound. The reef also attracts minke whales in April–May, and if you’re really lucky, blue whales (the largest animal ever to have lived) in December–January. For cross-border travellers wanting to combine this with a broader trip, booking flights through Trip.com AU/NZ flights can help keep the logistics simple.

Coral Bay: The Quiet Alternative

Coral Bay, 150 kilometres south of Exmouth, offers the same whale action with a fraction of the crowds. The Ningaloo Coast World Heritage Area here is shallow enough that you can snorkel with whale sharks in April–May and watch humpbacks from the beach in July–August. The Australian Institute of Marine Science (2023) notes that the coral cover here has improved 15% since 2018, making it one of the healthiest reef systems in the world. For whale watching, August to October is prime time, with the added bonus of seeing migrating manta rays and dolphins feeding alongside the whales.

Albany: The Southern Ocean Spectacle

Albany, on the south coast of Western Australia, is the last stop before the whales head back to Antarctica. The King George Sound here is a calving ground for southern right whales, which are slower and more approachable than humpbacks. The Western Australian Museum (2023) estimates that around 1,500 southern rights visit the sound between June and October. The best months are September to October, when the calves are strong enough to breach. The Torndirrup National Park offers cliff-top views that are so close you can hear the whales breathing. It’s a quieter, more intimate experience than the east coast — perfect for photographers and anyone who hates queues.

What to Bring and How to Watch Responsibly

Gear Up for the Elements

Whale watching in Australia means wind, sun, and sometimes rain — even in winter. We recommend: a windproof jacket (the spray off a whale’s blow can soak you from 50 metres), polarised sunglasses (cuts glare so you can see the dark shapes underwater), and a camera with at least 200mm zoom (phone cameras won’t cut it unless the whale is right beside the boat). If you’re on a cruise, bring binoculars and a dry bag for your phone.

The Rules of the Water

Australia’s National Whale and Dolphin Protection Plan (2023) sets strict rules: boats must stay at least 100 metres from a whale (300 metres for calves), and no more than three vessels can be within 300 metres at the same time. Drones are banned within 100 metres of any marine mammal in most states. If you’re swimming with whales in Ningaloo, you must use a licensed operator — the fines for going solo start at $10,000. The rules exist because stressed whales stop feeding and can abandon their calves. So keep your distance, turn off the drone, and let the whales come to you.

The Best Month, Coast to Coast

If you can only pick one month, September is the goldilocks of whale watching across both coasts. On the east coast, it’s the peak of the southbound migration — mothers and calves are playful, the weather is warming up, and the crowds are thinner than in July. On the west coast, September is the last month of the northbound run in Exmouth and the start of the southern right season in Albany. The Australian Bureau of Meteorology (2023) data shows that September has the lowest average wind speeds along the east coast (12 km/h) and the highest visibility on the west coast (20+ metres underwater). It’s the month where everything aligns.

FAQ

Q1: What is the absolute best time of year to see whales in Australia?

The best time is June to July for the northbound migration on both coasts, and September to October for the southbound leg. If you want to see mothers with calves, the southbound window is your best bet — specifically September on the east coast and October on the west coast. The Australian Marine Mammal Centre (2023) reports that 80% of humpback sightings in September involve at least one calf.

Q2: Can I see whales from the shore without a boat?

Yes, and in many places it’s better than a boat. The Cape Byron Lighthouse in Byron Bay, The Gap in Sydney, and Torndirrup National Park in Albany all offer excellent land-based viewing. The National Parks and Wildlife Service NSW (2023) estimates that over 60% of whale sightings in Sydney Harbour National Park are from land. Bring binoculars and a windbreaker.

Q3: How long does a typical whale-watching cruise last, and what’s the success rate?

Most commercial cruises run 2 to 3 hours. The success rate on licensed vessels is over 95% during peak season (June–October), according to the Whale Watching Industry Association of Australia (2023) . If you don’t see a whale, most operators offer a free return trip — but that rarely happens. The average sighting per cruise is 3–5 whales, with 1–2 breaches.
