Your once-in-a-lifetime chance to see the world’s newest comet

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.

From coast to mountains, hiking in Gippsland offers a stunning array of landscapes, with trails that take you deep into the region’s heritage.

I step out onto the sand and it cries out underfoot. Kweek! I take another step and there’s another little yelp. Screet! Picking up the pace, the sounds follow me like my shadow, all the way down to the water. It’s obvious how this spot got its name – Squeaky Beach – from the rounded grains of quartz that make the distinctive sounds under pressure.

For many, Wilsons Promontory National Park is the gateway to Gippsland , and the best way to explore it is by walking its network of hiking trails, from coastal gems such as Squeaky Beach through to the bushland, among the wildlife. But it’s still just a taste of what you’ll find on foot in the region.

Venture a bit further into Gippsland and you’ll discover the lakes, the rainforest, and the alpine peaks, each changing with the season and offering summer strolls or winter walks. Just like that squeaky sand, each step along these trails has something to tell you: perhaps a story about an ancient spirit or a pioneering search for fortune.

The best coastal hikes in Gippsland

Wilsons Promontory National Park (or ‘The Prom’, as you’ll end up calling it) is an easy three-hour drive from Melbourne, but you might ditch the car when you arrive, with much of the park’s 50,000 hectares accessible only by foot. From the inky water of Tidal River (dyed dark purple by abundant tea trees), I like the easy walks along the coast, among lichen-laden granite boulders, to golden beaches and bays.

The trail to the panoramic views at the summit of Mount Oberon is a bit harder, up steep timber and granite steps, but it’s a popular 6.8-kilometre return. The more remote hikes are found through the open banksia and stringybark woodland of the park’s north, or along the multi-day Southern Circuit , which ranges from about 35 to 52 kilometres, with sunrises and sunsets, kangaroos and cockatoos, and maybe even whales.

You might also see whales on the George Bass Coastal Walk , even closer to Melbourne on the western edge of Gippsland. This dramatic seven-kilometre trail along the clifftops takes in sweeping views of the wild ocean, occasionally dipping down from grassy green hills to coastal gullies and a secluded beach. It also now links into the Bass Coast Rail Trail for an extra 14 kilometres.

Over at the eastern edge of Gippsland, in Croajingolong National Park, you can wander along the lakeshores beneath koalas and around goannas (I keep my distance since one chased me here!). For those who are even more adventurous, the park is also the starting point for the 100-kilometre Wilderness Coast Walk , usually done over seven days.

Deep in the Long Tunnel Extended Gold Mine at Walhalla, mining guide Richard tells me how this small town in the mountains east of Melbourne boomed when prospectors found gold here in 1862. These days, you’ll find most of the town’s treasure – its heritage – above ground, with the Walhalla Tramline Walk a wonderful way to explore it.

Just seven kilometres long, the walk takes you through decades of Gold Rush history, following the original rail trail from lush bushland to the mining sites, and through the charming village of just 20 residents with its wooden cottages and old shopfronts adorned with turn-of-the-century advertising posters. Blazing a trail where trailblazers once opened up the region, this is also the starting point for the 650-kilometre Australian Alps Walking Track.

Nearby, Baw Baw National Park has walks through gnarled snow gums and alpine heaths that show off the colourful wildflowers in summer and the pristine carpet of white in winter. Several trails are perfect for snowshoes, including a 45-minute route from St Gwinear up to vast views across the Latrobe Valley.

Further up into the mountains, the Toorongo and Amphitheatre Falls Loop Walk is an easy 2.2-kilometre path that serenades you with the sound of flowing water as you pass mossy rocks and tree ferns en route to two sets of waterfalls cascading over boulders in the remote wilderness.

The best cultural hikes in Gippsland

Across a pool in a natural sandstone amphitheatre, deep within a cave behind a waterfall, it’s said the Nargun has its lair. A fierce creature, half human and half stone, that abducts children and can’t be harmed by boomerangs or spears, the story of the Nargun has been told around the campfires of the local Gunaikurnai people for generations.

As a culturally significant place for women, hikers are asked not to go into the Den of Nargun, but a 3.4-kilometre loop walk leads you through a rainforest gully to the entrance where you can feel the powerful atmosphere here in Mitchell River National Park , along Victoria’s largest remaining wild and free-flowing waterway.

The Den of Nargun is part of the Bataluk Cultural Trail , a series of important traditional Gunaikurnai sites through central Gippsland. Another location is Victoria’s largest cave system, Buchan Caves Reserve, with trails to important archaeological sites of human artefacts up to 18,000 years old. The FJ Wilson Interpreted Walk includes the naturally sculpted white limestone steps of the 400-metre-long Federal Cave, while the Granite Pools Walk goes among tall timber and moss-covered gullies.

Also important to the Gunaikurnai people is Tarra-Bulga National Park , known for its ancient myrtle beeches and enormous mountain ash trees. Just 40 minutes return, the Tarra Valley Rainforest Walk offers a taste of this verdant landscape, while the Grand Strzelecki Track takes you deep into the lost world of forest giants on an epic 100-kilometre trail rich with tradition.
