Quarantine Trig

Only the substantial concrete foundation of the Quarantine trig station at North Head remains, near the North Head Close Defence Observation Post.

The name plate is still attached to the vase, but there’s no mast or vanes.

There’s sweeping ocean views from the track up to the trig.

Getting to Quarantine trig
