Police detectives working to find out what happened to Sydney woman Lynette Dawson are back at square one after days of digging in the dirt beneath her former home yielded no clues about her disappearance.

Ms Dawson was 33 when she went missing from the northern beaches in 1982, leaving behind two daughters.

Her husband, Chris Dawson, has long been a suspect in the case but the former Newtown Jets rugby league player denies any involvement in her disappearance.

Investigators dug up the Bayview home for almost a week but found no human remains and no significant clues.

A police source on Monday told AAP the only things beneath the now torn-up lawn were large pieces of rock.

The investigation into Ms Dawson's fate must now turn back to other avenues beyond the family home.

Police said in a statement they are: "committed to providing answers to her family".

Contractors will restore and repair parts of the property affected by the dig.
