WWII triggered creation of Australia's only underground hospital at Mount Isa

As World War II inched closer to Australia, miners in Queensland's north-west volunteered their manpower to dig and fit out Australia's first — and only — underground hospital.
"Even though it was never used as a hospital, the nurses would come here after their shifts to sleep because it is so much cooler in the tunnels than it is outside.”
Ms Markowski said local miners volunteered their time and completed the work in just two weeks between March and April 1942.
"The miners drilled, blasted and mucked out a series of four tunnels," she said.
"Three run parallel to each other and the fourth intersects them, creating a capital E shape."
