A former police officer who attempted to stab his wife and two children to death at their Brisbane home three years ago is starting his life sentence in prison.
The 44-year-old, who cannot be named for legal reasons, repeatedly stabbed the 39-year-old woman and their children, aged nine and seven, at Carina on February 2, 2014.
The Brisbane Supreme Court on Tuesday heard he began planning the violent rampage after being confronted by his then-wife over his affairs with sex workers, which he at one point funded with her engagement ring.
He pleaded guilty to three counts of attempted murder before Justice Peter Flanagan, who sentenced him to life in prison.
"It is clear that you intended to kill your entire family," Justice Flanagan said.
The court heard the man, who resigned from the force in 2008 after serving 17 years, had timed the attack in the early hours of February 2 to coincide with police shift changeovers in the hope it would stall their response.
He used two large kitchen knives to stab his wife first, knowing she would be the most difficult to kill, before then attacking his son and daughter.
All three required surgery and have been left with permanent scarring, the court was told.
In a victim impact statement read to the court, the man's former wife spoke of her children's trauma and described her bodily scarring as a "road map" of an attack that could never be erased
"My children will carry this trauma with them for the rest of their lives, lives that I hope will be long despite the attempted efforts of their father to cut them short," the statement said.
She received 71 wounds while her daughter suffered more than 32.
The man will be eligible to apply for bail in February 2029.
