Man admits killing Sydney safecracker

A 71-year-old man has admitted killing Sydney underworld figure Lynn Tasman Jones eight years ago and dumping his body in the Royal National Park.

Donald Williams Reeves was due to face a murder trial in the NSW Supreme Court on Monday.

But he pleaded guilty to the June 2009 manslaughter of the 69-year-old former safecracker and fraudster, whose skeletal remains were discovered by bushwalkers four years later.

Reeves also pleaded guilty to unlawfully disposing of the victim's body.

His arrest in 2015 followed a tip-off to police two months after they announced a $100,000 reward for information about Mr Jones' killing.

At the time, police said the 1991 Camry owned by Mr Jones had not been found but a parking ticket issued to it around the time of his disappearance was paid in cash at a Sydney post office.

Justice Stephen Campbell adjourned the case to Friday for mention with a sentence hearing scheduled for June 13 and 14.
