Macquarie Street at Circular Quay is closed due to a gas leak at the Sydney Opera House.

Fire crews were called to the area just after 3PM and set up a 100 metre exclusion zone about 3pm on Tuesday after a small excavator hit a gas line.

Approximately 500 people have been evacuated from the Opera House concourse area and adjoining restaurants while firefighters in protective gear monitor the gas levels.
