The agonising wait for news may finally be over for the parents of Matthew Leveson following the discovery of bones in the Royal National Park.

Now questions have arisen about what this find will mean for his boyfriend Michael Atkins, who has previously been acquitted of Mr Leveson's murder, but who led police to the site where the bones have been found.

It's nearly a decade since the 20-year-old went missing after leaving a nightclub.

Mark and Faye Leveson have never given up on finding their son. Today, human bones thought to belong to Mr Leveson were found in bushland just off Waterfall Road.

Mr Leveson was last seen leaving ARQ nightclub in Darlinghurst in September 2007 with his boyfriend Michael Atkins.

Mr Atkins was charged, then acquitted of Mr Leveson's murder.

During an inquest last year, Mr Atkins lead police to the National Park, indicating he believed Mr Leveson was buried there.

The information was only offered after Mr Atkins was granted immunity for lying under oath at Leveson's inquest.

A search in November, and another in January, were unsuccessful, but the location where the bones were found today is where Mr Atkins had indicated Mr Leveson might be.

This afternoon at 3pm, an excavator suddenly stopped and police told the Levesons they had "dug up" something of interest.
