Ashes to OMG
From devastation to wonder as Kangaroo Island bushfires lead to cave discoveries
From fire to 'OMG': New caves wow, commenters debate nature healing vs muddy caving
TLDR: After the 2019 fires, explorers uncovered 150+ hidden caves on Kangaroo Island, including the “Phoenix” cavern. Commenters cheered the island’s regrowth, cited sources saying Aussie nature rebounds after burns, and traded caving war stories—dry South Australia vs muddy UK—while cautioning against romanticizing disaster.
Kangaroo Island’s darkest days birthed an underground plot twist: after the 2019 fires scorched nearly half the island, researchers followed telltale sinkholes and uncovered 150+ new caves, including a million-year-old beauty first dubbed OMG and later crowned Phoenix. In the comments, the vibe whiplashes between heartbreak and hope. One traveler paints a cinematic comeback—black trunks wrapped in neon-green shoots—while another cites Lonely Planet to argue that Aussie ecosystems can bounce back. The unspoken tension? Folks love the wonder, but some flinch at celebrating discoveries born from disaster.
Then the cavers showed up and turned it into a mud-slinging (literally) culture clash. A South Australia veteran flexes that SA caves are mostly “horizontal and dry,” while a UK expat grumbles that British caves are a “muddy wet affair… too many ropes.” Cue friendly ribbing about who’s tougher: the chalk-dusted crawlers or the soggy rope wranglers. Aesthetic fans chimed in to crown the ABC photos as gallery-worthy, and meme-lords decided OMG might be the most honest cave name on record. The consensus ending? Nature’s phoenix moment is real, the photos slap, and the underground still feels like a last frontier—even if half the thread is still drying their ropes
Key Points
- •The 2019 bushfires on Kangaroo Island burned over 200,000 hectares (about half the island), killed two people, destroyed nearly 90 homes, and severely impacted wildlife and livestock.
- •Post-fire clearing allowed researchers to use aerial imagery to identify surface depressions and guide cave exploration.
- •Cavers including Matt Smith and Andrew Stempel discovered a major cave in March 2021, initially dubbed “OMG” and later named “Phoenix.”
- •The Phoenix cave features an eight-metre entry drop, delicate limestone formations, and tunnels extending hundreds of metres; the caves are estimated to be 1–2 million years old.
- •Surveying revealed more than 150 new caves on Kangaroo Island, up from about 130 known before the fires.
