Port Noarlunga, south of Adelaide, is best known for its fishing jetty, but it also has landbased opportunities.

In 2025 the southern section of a raised coastal walkway called the Witton Bluff Base Trail was opened. This walkway runs north along the rocks from near the jetty.

At high tide some of the rocks along this walkway drop into deep water, a likely spot for chasing mulloway and more.

Nimble fishos could, with care, climb over the railing at several locations to access the rocks, but check the latest by-laws first, which are likely to evolve.

The walkway was still being built when we checked it out, and it remains to be seen if a gate will be built for fishermen to access the rocks.

Landbased fishos can also fish the mouth of the Onkaparinga River nearby.

Here is the SA seasonal fishing calendar for various fish species.
