This rare flower is about to bloom in Sydney – but only for 24 hours

It will be the first time the flower has opened in over a decade.

While a trip to the Botanic Gardens of Sydney is always a good idea, there’s an especially exciting reason to visit right now. One of the rarest flowers on Earth is about to bloom, a phenomenon that only happens every 15+ years.

The catch? It’s also the worst-smelling plant in the world, nicknamed the ‘Corpse Flower’ thanks to its vile odour. We speak exclusively to onsite horticulturalist Wayan ‘Eka’ Diana to learn how you can witness this extraordinary natural marvel, and if the smell really is that bad.

What is the Bunga Bangkai or Corpse Flower

This morning, Botanic Sydney opened Putricia, the Corpse Flower, to the public as she is expected to bloom any minute now. Would you like to see (and sniff) the world's most pungent flower?

Originating from the rainforests of western Sumatra in Indonesia, this rare and endangered plant species produces one of the largest flowers in the world. But unlike many floral varieties, it doesn’t bloom perennially or even annually.

The Bunga Bangkai at the Botanic Gardens of Sydney is named ‘Putricia’. This species flowers roughly once every two decades and can reach a staggering height of over three metres. In fact, it’s the tallest flower in the world, breaking records in 2010 after an inflorescence in New Hampshire measured 10 feet 2.5 inches tall.

The name comes from the Indonesian words ‘bunga’ – meaning flower – and ‘bangkai’, which roughly translates to ‘corpse’. This was no mistake either – the flower is most commonly known for its distinct smell.

Those lucky enough (or some may argue, unlucky enough) to witness the flower in full bloom have described it as pungent and fetid. Personal recounts range from the mildly unpleasant aroma of wet socks to the unmistakable stench of rotting flesh.

“The last time I saw it in full bloom was in Bali. It was really unpleasant, like the smell of a dead animal," Eka recalls when asked about the smell.

But equally reported on is the Bunga Bangkai’s immense beauty. With its huge, wine-red petals and towering yellow flower spike, it’s unlike any other flower on Earth.

When and where will it bloom?

The Corpse Flower is housed in the Ariod Glasshouse at the Botanic Gardens, arguably one of the best places to visit in Sydney. The peculiar plant has multiple offshoots, all in different stages of growth. And at the start of 2025, one limb in particular started showing signs of blooming.

Onsite horticulturalists conducted a series of tests, measuring the plant daily and consulting blooming patterns of Bunga Bangkai around the world before confirming the flower is preparing to open within the next week.

“It’s only a matter of days," says Eka. “We’re predicting it will begin to bloom at some point between today [16 January] and the 20th of January."

Those hoping to catch a glimpse should be quick though – once fully unfurled, the corpse flower only stays open for up to 24 hours before wilting. While it’s currently unavailable for public viewing, staff will generously move the plant to Palm Grove House when its bloom period begins, which will remain open from 8am to midnight to allow visitors to take full advantage of the short 24-hour bloom period.

With various Corpse Flowers in the collection, this will be only the fifth time one has blossomed at the Royal Botanic Gardens of Sydney, preceded by blooms in 2004, and an incredible double flowering in 2006, 2008 and 2010.

Keep a close eye on the Royal Botanic Garden’s website for live updates . We certainly will be!

8 ways to discover a new side of Port Stephens

Aussies might think they know what Port Stephens is all about – but it’s time to take another look.

You might’ve driven through this NSW coast town. Maybe even stopped for fish and chips or a quick dip. But spend a long weekend in the new Port Stephens , and you’ll seriously regret not doing it sooner. We’re talking treks across beaches, reef dives and up-close time with rescued koalas.

All in all? It only takes a day before you see Port Stephens in a whole new light, and not much longer until it’s locked in as your favourite family destination.

1. Stockton Sand Dunes

Port Stephens incredible Stockton Sand Dunes are the largest moving sand mass in the Southern Hemisphere. They shift like an endless magic trick across the Worimi Conservation Lands , a 4200-hectare coastal co-managed by the Traditional Owners.

Tear over them in a 4WD. Rev through valleys soft as melting ice cream on a quad. Carve down 30-metre slopes on a sandboard. However you choose to cross them, you’re guaranteed a seriously wild ride.

2. Scale Tomaree Head Summit Walk

A short climb through bushland opens up to the coastal drama of Tomaree Head . Spot Zenith, Wreck and Box Beaches. See the Fingal Island lighthouse and offshore rookeries where Australia’s rarest seabird, the Gould’s petrel, nests.

History buffs can’t miss the WWII gun emplacements. And if you’re hiking between May and November, bring binoculars. Travelling whales might just be breaching below.

3. Watch out for whales

You’ve seen the spouts of migrating humpbacks and southern right whales from shore. Set sail from Nelson Bay to see them up close. Cruise straight into the action, with tail-slaps, barrel rolls and all.

And they’ve got competition from the local show-offs. Port Stephens bottlenose dolphins leap and play. Some tours even spot pudgy fur seals, spending lazy days soaking up the sun on Cabbage Tree Island.

4. Port Stephens Koala Sanctuary

Pop into the Port Stephens Koala Sanctuary  to learn about the rescued koalas who climb, nap, snack and heal in this natural patch of bushland. Wander the immersive Sanctuary Story Walk to discover more about their habits, then head to the SKYwalk – a treetop platform constructed for spotting these eucalyptus-loving locals. Peek into the hospital’s viewing window, where sick or injured koalas may be resting in their recovery enclosures.

Not enough time around these adorable marsupials? Stay overnight in silk-lined glamping tents.

5. Diving Port Stephens

Port Stephens has some of NSW’s best dive spots. At Fly Point, float through sponge gardens and coral castles thick with nudibranchs (AKA sea slugs). Halifax Park has blue gropers and crimson-banded wrasse, while Shoal Bay’s seagrass meadows hide pipefish, cuttlefish and octopus.

Accessible only by boat, Broughton Island is home to a vast array of marine (and bird) life. Snorkel with blue devilfish and stingrays at sites like The Looking Glass and North Rock. More experienced divers can head out with one of the many PADI-certified operators.

At nearby Cabbage Tree Island, expect to see shaggy-faced wobbegongs cruising along.

6. Irukandji Shark and Ray Encounters

Not quite ready to dive in? Irukandji Shark and Ray Encounters is the perfect way to spot local marine life without getting too deep. But there’s no obnoxious glass tank tapping here. Instead, this interactive aquarium allows guests to wade into natural-style lagoons that mimic the real thing.

Gently pat Port Jackson and bamboo sharks, hand-feed rays, and feel their sandpapery skin with your fingertips. It is all under expert guidance. If you want to go deeper, pop on a wetsuit and swim alongside tawny nurse sharks, white-tipped reef sharks and zebra sharks in the lagoon.

7. Fish the estuaries

Fishing fanatics will fall for Port Stephens hook, line and sinker. Here, one of the largest estuary systems in the whole state sees tidal rivers and mangrove ecosystems. Waterfronts are thick with oysters, and residential fish that might include anything from bream, whiting and flathead, to blue swimmer crabs, kingfish and longtail tuna.

If you prefer to choose your own adventure and fish offshore, you can hire a boat from one of the marinas and set your own course.

8. Taste new Port Stephens flavours

With plenty of activity to fill your days, refuelling on delectable cuisine becomes equally important. And Port Stephens answers the call.

Pop into Holbert’s Oyster Farm for fresh-farmed Port Stephens rock oysters and Pacific oysters, Australian king and tiger prawns, as well as a variety of tasty sauces to try them with.

Take a group to Atmos for an authentic Greek experience over large shared dishes and Greek-inspired cocktails. Or feast on sea-to-plate, modern Australian dishes at the pet-friendly Restaurant 2317.
