O'Brien's Road is one of the oldest roads constructed in the suburb of Figtree, New South Wales, Australia. O'Brien's Road was constructed in 1821 by Cornelius O'Brien. It runs between Mount Keira and Mount Kembla. O'Brien built the road because he had been looking for an easier way into the Illawarra district than the one Throsby Track at Bulli, which was dangerous due to its extreme steepness.
