Jim Adams, 65, died when he was struck by a pressurised water pipe while working on the tunnel’s Wilson Road site at Pennant Hills.
Mr Adams’ eldest son James also died in a tunnelling accident at the Dartbrook Coal Mine in the Hunter Valley in 2004 when the two were working side-by-side. “Dallas Adams described the personal impact as brutal and said he finds it incredibly difficult to wake up every day,” Judge David Russell said.
