A broken gas main caused disruption at a popular Mona Vale scenic location.

Just before 9.15am yesterday morning (Sunday, 02 July), Fire and Rescue NSW Mona Vale Station responded to a report of a gas leak at Narrabeen Park Parade, Mona Vale.

They found the leak close to the popular Robert Dunn Reserve at the southern headland of Mona Vale Beach.

A thick smell of gas was present and the force of the underground rupture had caused around 3m of the roadway to collapse.

Firefighters immediately established a hose line for fire protection, and set up an exclusion zone, closing Narrabeen Park Parade in both directions and calling for a repair crew to attend urgently.

With natural gas lighter than air venting up into the atmosphere, the immediate risk to nearby residents was deemed acceptable to allow people to remain in their homes.

The road remained closed to pedestrians and traffic however due to the proximity to the ruptured main.

Firefighters were forced to call for the assistance of NSW Police to maintain the road closure when some members of the public ignored the directions not to enter the area.

Jemena contractors were on scene from 9.30am, but the nature of the leak required heavy equipment to be brought in to excavate around the pipe.

It is understood than an initial attempt to repair the leak was unsuccessful when the repaired section ruptured again, forcing workers to conduct a secondary repair, which sealed the leak just after 1.30pm.

Once the danger had passed, firefighters from Mona Vale Station and officers from Northern Beaches Police Area Command departed the scene just after 1.45pm, leaving the remainder of the repair work in the hands of Jemena contractors.
