Was anyone held responsible?
Mine manager Matthew Gill faced an intense grilling over the collapse, with serious questions raised over whether it was safe to mine at the levels where the workers were found, despite a rockfall at the same depth a few months earlier. But a coronial inquest found neither the company nor any individuals were responsible for Knight's death.
What was the impact on the survivors?
Speaking ahead of the 10-year anniversary, Russell and Webb revealed their mental scars. Russell reached out for help only after his wife and kids threatened to walk out. "The person I became after being stuck underground was a monster," he told Nine's 60 Minutes. Webb had thought he was coping but a recent run-in with an employer sent him into a downward spiral of aggression, depression and panic attacks and he's still angry about Knight's untimely death. "It's beyond comprehension - you dig a hole, it's going to fill in, every fool knows that, but apparently the people that did the inquiry didn't know that," he said.
When will the rescue be marked?
Tasmanians are expected to commemorate the recovery effort on May 9.
