Victorian Alps disappearance: the friends who went into Australia's wilderness and never came back

Russell Hill and Carol Clay are thought to be dead. But technically they're still just missing

A year ago, two friends in their 70s went missing in some of the wildest terrain in Australia: Wonnangatta Valley. It's the sort of place where you might go days without seeing anyone, with only kangaroos and snakes for company. A place of snow-capped mountains - even in summer. A place of bushfires and danger.

The sort of place where it's easy to get lost.
