NSW RFS Commissioner Shane Fitzsimmons on his last day and moving on to head disaster agency

Over Australia's Black Summer, Shane Fitzsimmons led the fight against the bushfires that burned all over New South Wales.

As the Rural Fire Service (RFS) Commissioner, he was on the front line as families grieved the loss of firefighters and those unable to escape the ferocity of the blazes. There's "no way", he says, anyone could come out unscathed.

"I wish we had the ability to put out every fire before they became a large fire," he says.
