secret military bunker ☹

During World War II, Bankstown was a hub of military activity as the airport was home to several fighter units.

As a result, the military set up loads of "dummy houses" to make the airport look like a farm, and built several secret bunkers underground where training, plotting, and other covert operations took place.

Several of the bunkers are public knowledge but one continues to elude conspiracy theorists. Rumoured to house military secrets, it is said to lie untouched beneath a block of flats in the area, its steel doors welded shut. Some intrepid explorers claim to have snuck inside in the 1980s to find a vast, Indiana-Jones-style complex with tunnels connecting to a secret military headquarters nearby.
