A man who died after being found unconscious in a backyard pool in Sydney is reportedly former judge Richard Gee.

NSW Ambulance paramedics were called to a home in Belrose in northeast Sydney at about 10pm local time yesterday, but the 83-year-old died at the scene.

The Nine Network and Fairfax Media report the victim was Gee, who was targeted in a series of attacks on judges and others linked to the Family Court in the 1980s.

Gee and his family survived an explosion at their Belrose home in 1984.

Police are investigating the death and will prepare a report for the coroner.

More than a dozen people have died from drowning in NSW over the holiday period, prompting authorities to warn the public to be careful around water.
