A man who tried to kill his two young children by creating an explosion in his car has been sentenced 20 years in prison, with a 15 year non-parole period.
Paul Brian Edward Connelly, of Burnie, barely blinked as his sentence was handed down by Chief Justice Alan Blow in the Hobart Supreme Court today.
In handing down his sentence Chief Justice Blow said Mr Connelly decided to kill the boys aged 5 and 8 in order to spite his wife.
Chief Justice Blow said this was an attempted murder worse than most others, and that there were two victims who received life threatening injuries and will have ongoing intense treatment and as his father he had a duty to protect them.
''Attempting to kill them involved the worst possible breach of trust,'' Chief Justice Blow said.
The incident occurred at Shorewell Park in December last year.
