From the industrial edge of the city to remote corners of the state, these sites offer a glimpse into a forgotten world. Here are five of the most atmospheric ruins you can still see today, legally and safely, all from our guide Hidden Gems NSW.

5 Abandoned Places in Sydney & NSW

1. The Industrial Cathedral: Lithgow Blast Furnace

On the edge of the Blue Mountains, this is the birthplace of the Australian steel industry. Walking among the towering brick arches feels like stepping into a medieval ruin. It's one of the premier industrial heritage sites in the state and a holy grail for night photographers. It's a free, open-air ruin, but don't climb the walls or take any stones or metal.

2. The Ghost of the Valley: Newnes Shale Oil Refinery

If you're looking for abandoned towns in NSW, Newnes is the gold standard. Once a thriving shale oil town, it's now a haunting collection of ruins slowly being swallowed by Wollemi National Park, including the iconic "beehive" coke ovens. Stick to the walking track and leave every brick where it lies.

3. The Subterranean Secret: Glenbrook Tunnel

Tucked away in the lower Blue Mountains, this is a top pick for abandoned places on Sydney's outskirts. The S-shaped rail tunnel has a dark history involving secret wartime storage and moody, atmospheric architecture. The tunnel is closed while Blue Mountains City Council works towards opening it as a public path, so the only way inside for now is one of council's occasional booked open days. Don't cross the fencing.

4. The Seaside Fortress: Hill 60 Bunkers

At Port Kembla, Hill 60 is a network of concrete bunkers and tunnels that served as coastal defence during WWII. The contrast between the rugged concrete ruins and the working steelworks below makes it a unique spot for photos. Hill 60 is also a heritage-listed Aboriginal site, and the military tunnels are closed to the public, so enjoy it from the lookout and paths.

5. The Fortress of the North: Fort Scratchley

While many abandoned buildings in Sydney are left to decay, Fort Scratchley in Newcastle has been preserved to tell the story of the "Battle of Newcastle." It remains the only Australian fort to have engaged an enemy vessel at sea. The grounds are free; its tunnels are open on booked guided tours.

How to Visit Abandoned Places Safely

Finding these places is only half the story; knowing the history and the right way to visit them is what turns a weekend drive into something special. Old ruins can be unstable, and many are heritage-protected or on private land. Stay on tracks and behind fences, never enter closed tunnels or buildings, take nothing, and use official tours where they exist.
