Small boat operators must not anchor, moor, drift or engage in fishing activities within a transit only zone. The purpose of designating a transit only zone is:

• to avoid potential collisions between small boats and large commercial ships
• for the safety of small boat operators and their passengers.

A transit only zone in Port Phillip Bay extends from Point Gellibrand (Williamstown) south to an imaginary line at latitude 38° South.

Victorian Recreational Boating Safety Handbook Yellow ‘special mark’ light buoys are used to define the boundary zone (see map).

Shipping channels and their approaches are high shipping hazard areas. Small boat operators should exercise caution and steer well clear in these areas.
