This may just be the celestial event of the century.
Look up into the night sky this October and you may just catch a rare celestial visitor. Known as C/2025 R2 (SWAN), it takes more than 600 years to pass Earth. In other words, this is the first and last time you’ll ever be able to see it.
What makes C/2025 R2 (SWAN) so special?
Identified on 11 September by an amateur astronomer in Ukraine, C/2025 R2 (SWAN) is a completely new visitor to our solar system. Vladimir Bezugly, from the central Ukrainian city of Dnipro, first spotted the comet when viewing images from SOHO (Solar and Heliospheric Observatory), a joint-project spacecraft between NASA and the ESA tasked with observing the sun.

C/2025 R2 (SWAN) seemingly appeared out of nowhere, a “bright blob" moving close to the sun. It’s not only one of the brightest findings ever made via SOHO, but also happens to be one of the newest comet discoveries in the world. Characterised by its gorgeous green glow and exceptionally long tail (the stream of gas and dust left in its wake), it’s a true sight to behold – and you’ve got one opportunity to catch it.
Experts have been working hard to learn more about the object, which has been classified as a long-period comet with an orbital cycle of over 600 years. For context, Earth’s orbital cycle is just one year, meaning that’s how long it takes us to complete one full lap around the sun. So if C/2025 R2 (SWAN) is about to pass Earth, it won’t be back until 2625.
What’s the likelihood of seeing it in Australia?

At its most recent, C/2025 R2 (SWAN) clocked a magnitude of +7 (magnitude being the scale astronomers use to measure the brightness of celestial objects). The lower the number, the brighter the object, with +6.5 considered the limit for naked-eye visibility under a non-polluted sky.
While C/2025 R2 (SWAN)’s rating is relatively low compared to others of its kind – Halley’s Comet sat at +2.1 and 96P/Machholz at +2.2 when they last passed Earth – it doesn’t mean you won’t see it. Our interstellar guest is estimated to pass through around mid-October, approximately 40 million kilometres away. For us Earth-dwelling folk, that sounds quite far. But in space talk, it’s quite the opposite!

Hot tips for comet chasers
While a celestial sighting can never be guaranteed, there are definitely ways to improve your chances. One of the easiest ways is simply finding a patch of sky as far-removed from the big smoke as you can get. Light pollution significantly decreases the likelihood of catching an astronomical event, because it’s artificial, it washes out fainter light, reducing the overall contrast of the sky and preventing the human eye from fully adjusting to the dark.
That’s why places like the outback, national parks and other areas are among Australia’s best stargazing spots – they’re isolated by design. Or head to Kestrel Nest EcoHut in NSW, the first official International DarkSky Approved Lodge in Australia.

Be sure to pack a good pair of binoculars, too. For those who take the sport a little more seriously, opting for a telescope is your best bet. You’ll also want to bring a camp chair, bug spray, blankets, snacks and a red-light lamp. If you’re determined to catch the show, you may be waiting for a while, so these items will not only keep you comfy but also allow you to stay out later and for longer.
Aussies usually aren’t too lucky when it comes to catching comets, but it seems the odds are in our favour this time. Right now, C/2025 R2 (SWAN) has primarily been visible from the southern hemisphere. Currently tracking further from the sun and closer to Earth, it will reach perigee (its closest point to our planet) on 21 October. C/2025 R2 (SWAN) will then continue on its centuries-long orbit, making this a truly once-in-a-lifetime experience.

The Great Ocean Road has captured the hearts of Australians with its astounding scenery since 1932, but going off-course can enrich your experience with untouched nature, foodie delights and charming towns.
It’s a chilly 16 degrees. My husband pulls on a steamer and jogs – as all seasoned surfers do – into the water. We’re at Bells Beach, the legendary break on Victoria’s Surf Coast that’s home to the Rip Curl Pro, the world’s longest-running event in competitive surfing. Each year, over the Easter long weekend, up to 40,000 people descend on the region for the event. Today, though, we have the beach almost to ourselves, and the less-than-favourable temperature doesn’t deter my husband from surfing this famous break.

Torquay to Anglesea and Aireys Inlet

The nearby surf town of Torquay marks the starting point for the Great Ocean Road. Unfolding our map, which we have marked out with a highlighted route for our children to follow, we set off for lesser-known Anglesea, a chilled-out town 20 minutes south of here. Its wide, sandy beach is a gentler swimming option for our young family. Groms can learn to surf here with Go Ride a Wave, which also runs stand-up paddle boarding on the Anglesea River.

After a couple of nights in Anglesea, we hit the road again, first stopping at Aireys Inlet. Here we stretch our legs at Split Point Lighthouse, which was made famous by the 1990s television series Round the Twist, before driving under the Memorial Arch that welcomes us, officially, to the Great Ocean Road.
This 243-kilometre coastal road was built by returned First World War servicemen and serves as a permanent memorial to those who fought and died during the war. Carved into rock using hand tools and horse-drawn carts, it was a huge engineering feat and provided much-needed access to isolated coastal communities.
Lorne to Birregurra
Lorne is a delightful beachside stop for lunch and browsing boutique stores. It’s also the gateway to Great Otway National Park, which comprises a varied landscape of old-growth forests, cool-temperate rainforests, heathy woodlands and rugged coast. With the highest rainfall in Victoria, the region is home to many waterfalls – 10 of which are within 10 kilometres of Lorne.
Turning slightly off the main drag, we wind along a gum-shaded road to Erskine Falls. Here, our son leads the way through the hyper-green rainforest and down 200-plus stairs to the cascade that drops 30 metres into a lush fern gully. We hop over large boulders to get closer to the falls, enjoying the entire place to ourselves; it’s worth the return climb.
From Sheoak Falls Picnic Area, there are walking trails to Henderson Falls, Phantom Falls, Won Wondah Falls and Kalimna Falls, some of which follow an old timber tramway from forest-logging days, which only came to an end in 2008.

You can follow your appetite north to the town of Birregurra, which is part of the Otway Harvest Trail that connects farm gates, markets, wineries, breweries and distilleries. It’s home to three-hatted modern Australian restaurant Brae, helmed by celebrated chef Dan Hunter, set among native gardens and an organic farm, and Otways Distillery, which produces small-batch spirits using local produce and botanicals.

Apollo Bay to The Otways
Back on track, the cliff-hugging stretch between Lorne and Apollo Bay is breathtaking. At Teddys Lookout, we overlook the winding road ahead and St George River spilling into the ocean. We spend languid days in Apollo Bay, a buzzy seaside town that boasts a three-kilometre-long, crescent-shaped beach with a backdrop of rolling green hills. One evening, as the sun sets, we take the steep 10-minute walk to Marriners Lookout, which affords panoramic views of the ocean, hinterland and town.
A 15-minute drive along the road, Maits Rest is a lush rainforest gully that has been protected since the early 20th century. Wandering along the 800-metre boardwalk, we inspect the delicate moss-covered forest floor and the gnarled roots of 300-year-old myrtle beech trees, then crane our necks to see their canopies, some 50 metres above us. It’s therapy in nature.
Cape Otway to the Twelve Apostles

The southernmost tip of Cape Otway is a delightful detour, home to the 1848-built Cape Otway Lightstation, the oldest surviving lighthouse on mainland Australia. We climb the narrow winding staircase to the gallery deck, explore the keepers’ quarters and telegraph station, and enjoy a coffee and some ‘famous’ scones at the charming onsite cafe.
It’s a pinch-me moment to finally see the Twelve Apostles in person. This unmistakable cluster of limestone stacks rising abruptly from the sea were never 12, however. When coined this in the 1890s as a marketing ploy, there were only nine; today, only seven remain after two collapsed in 2005 and 2009. We admire these Aussie icons from the viewing platform, in awe of Mother Nature’s ever-evolving artwork.
The Grotto is another natural attraction within Port Campbell National Park. (Image: Carmen Zammit)
Edging the wild Southern Ocean, this part of the coast – dubbed Shipwreck Coast – is made up of many sea-carved natural wonders including London Bridge, The Grotto and Gibson Steps. After exploring the lookout trails of Loch Ard Gorge/Poombeeyt Kontapool – its English name taken from the site of the 1878 shipwreck – we nestle into the sandy beach encircled by towering sandstone cliffs, as our children splash about on the water’s edge, and soak it all in.
Port Campbell to Timboon

Just north of Port Campbell National Park, the region of Timboon is part of the 12 Apostles Food Artisans Trail, filled with purveyors of delicious foodstuffs such as Timboon Fine Ice Cream, Timboon Railway Shed Distillery and Apostle Whey Cheese. As an antidote to the indulgence, the 20-kilometre Poorpa Yanyeen Meerreeng Trail is a self-guided ride or walk between Port Campbell and Timboon through tall forests, over historic bridges and past sparkling lakes and farmland with grazing cattle.
Warrnambool to Port Fairy

In Warrnambool, a town rich in maritime history, we take the four-kilometre Thunder Point Walk that traces the coast. The kids squeal when an echidna shuffles out from beneath the wooden boardwalk, and we stop to admire a seal lazing on a rock at the port.
Further along, the streets of quaint fishing village Port Fairy are lined with 19th-century cottages, old stone churches and Norfolk pines. Follow the historic walking trail to see some of the 60-plus National Trust buildings. Port Fairy is also home to Port Fairy Folk Festival (6-9 March), one of the country’s longest-running music and cultural festivals. You could time your road trip with the event for a fittingly celebratory end to any journey.
The Great Ocean Road can easily be done in three days, but we’ve spent a week on the road. The highlighted line on our now creased and well-worn map doesn’t follow the famous route precisely. It has sprouted branches in many directions, leading us to untouched rainforest and charming rural towns filled with culinary delights, and where we experienced some of our most memorable moments on the Great Ocean Road.
