The search for the body of missing man Matthew Leveson has resumed for a fifth day in the Royal National Park south of Sydney.
Police said the focus would remain on an area of bushland adjacent to a roadside parking area near the start of a walking track.
Last week, homicide detectives were led to this spot by Michael Atkins.
The area is now a crime scene, cordoned off by police tape.
Matthew’s parents Mark and Faye Leveson have been at the scene each day, watching as an excavator moves back and forth, clearing the undergrowth and ploughing up the loamy soil.
“It’s testing the patience,” Mark Leveson said this morning.
“But the police are here for as long as it takes and so are we. We are in this for the long haul.”
Mr Atkins was tried and acquitted of Matthew Leveson’s murder back in 2009 after a trial during which he exercised his right to silence.
Earlier this month, at an inquest in Sydney he was compelled to give evidence for the first time about his boyfriend’s disappearance.
