For one, the mine shaft was deep. The kangaroo was trapped on a "floor" of debris 32 feet below the surface, but the mine shaft could be hundreds of yards deeper beneath the unstable floor. Daylight was also fading fast, and the rescuers had to work quickly to save the kangaroo's life.
Manfred Zabinskas, a Wildlife Victoria volunteer, knew what to do. He was an experienced rock climber, and had previously scaled trees to rescue entangled birds, or to capture injured koalas after dog attacks or bushfires. For this operation, Zabinskas decided to rappel into the mineshaft. But he knew he'd have to be very careful.
