A crime scene has been established at Mollymook after human remains were washed up on the beach.
At 6.30pm on Friday, officers from the South Coast Police District were called to the beach after the remains were discovered.
The remains have been sent for forensic testing and as yet no link has been made to Sydney woman Melissa Caddick, whose decomposed foot was found on a beach near Tathra this week.
Police were called to Mollymook around 6.30pm on Friday after the remains were discovered by members of the public.
The grisly find was reportedly a large chunk of stomach flesh, including a bellybutton.
A NSW police spokesman told AAP a crime scene had been set up.
"The remains will be forensically examined. Inquiries continue," he said.
The gruesome discovery comes a day after DNA testing confirmed a decomposing foot encased an ASICS shoe that washed up near Bermagui, 150km further south, belonged to the missing mother.
Ms Caddick vanished the day after corporate watchdog ASIC executed a search warrant at her luxury Dover Heights home on November 11.
Liquidators allege the self-styled financial adviser "meticulously and systematically" deceived those who entrusted millions of investment dollars to her over seven years, then used the money to fund her lavish lifestyle.
Ms Caddick's foot was on February 21 found by campers at Bournda Beach.
The remainder of her body is yet to be located.
Assistant Commissioner Mick Willing on Friday told reporters foul play against Ms Caddick was possible but suicide was more likely.
