Boolboonda Tunnel - QLD

Walk or drive through this 192m tunnel, the longest unsupported tunnel in the Southern Hemisphere!

If the tunnel is approached from Gin Gin (east side) it is clearly signposted on the left and close to the Gin Gin - Mt Perry Rd. After passing through the tunnel the trail winds for 3km back to the main road giving a good sense of the terrain the trains had to battle through. Here there is a sign (if coming from Mount Perry, west side) reading 'Tourist Drive 6'. It is then about 12km to the historic mining town of Mt Perry. The rail line corridor is still visible in places from the road but what remains is difficult to follow and after leaving the trail portions of it is on private land

The tunnel was constructed in 1883/1884 as part of a railway from North Bundaberg to Mount Perry. This section of the line closed in 1960. Most of the old railway reserve is now road reserve making it unlikely that the trail could be extended.

The trail is managed by the Kolan Shire Cuncil.
