%X An oceanographical investigation of coastal waters off Laurieton, N.S.W. (31º 39'S.) during August 1968 to March 1974 has shown that upwelling was a regular feature of the spring and summer season. This upwelling was confined to a 5-mile zone against the coast, occurred at intervals between 12 and 57 days, was of short duration (9-15 days complete cycle) and originated in offshore 15-17º C waters around 125-275 m depth. Upwelling velocities during the final stzges of development were between 17 and 34 m per day. Causes of the upwelling could not be determined. However, it is possible that the narrowing of the shelf width just north of Laurieton is a local factor of importance.
