Gas leak forces evacuations in Bondi

A gas leak at a Bondi construction site has forced the evacuation of 15 people from neighbouring buildings.

Crews were called to Old South Head Road, near Curlewis St, about 1pm (AEDT).

A NSW Fire and Rescue spokeswoman told AAP the leak appears to be coming from a busted gas main at the construction site.

Crews are conducting atmospheric testing at the site.

Emergency services have closed Old South Head Rd between Warners Avenue and O'Sullivan Rd.

Route 386 and 387 buses are diverting away from the area and may face delays.

There are no reports of injuries.

At 3.30 pm (AEDT) Old South Head Road was reopened and people were allowed to return to evacuated buildings.

"The incident has been shut down," NSW Fire and Rescue superintendent Ian Krimmer said.
