Sometime during the war, a United States Navy PT boat slipped into Cleveland Bay after dark without signalling, and the gunners on Magnetic Island sent a warning shell across its bow - the only shot these batteries are ever believed to have fired in the entire conflict. That single round captures the strange truth of the place. Two big coastal guns were dragged up a mountainous granite headland, concrete command posts and a searchlight tower and a radar station were poured into the boulders, hundreds of men lived and watched and waited here for a Japanese fleet that never appeared. Today the same path that supplied those gunners climbs through dry hoop-pine forest to the observation post on the ridge, and the most likely thing to ambush you is a koala, asleep in the fork of a gum, indifferent to the war it slept through.

The engineers anchored everything into the existing granite, threading concrete between car-sized boulders on a steep, heavily...

The feared push down the coast was blunted in the air and at sea - in the Coral Sea, over the Owen Stanley Range, in the long grind of New Guinea - and the front rolled north and away. The shells stayed in the magazine. When the war ended...

When Magnetic Island National Park was established, the Queensland parks service took the ruins under its wing, ran signs and pathways through them, and turned a derelict battery into one of the island's best-loved walks. The Forts Walk is now a roughly 3.8-kilometre return climb...
