Notice 2016-72: Construction works, replacement of Old Mandurah Traffic Bridge, Pinjarra Road
Old Mandurah Traffic Bridge - Pinjarra Road, Mandurah Estuary
Mariners are advised that construction works to build a replacement for the 'Old Mandurah Traffic Bridge' (Pinjarra Road) are underway and are anticipated to be completed by 30 November 2017. Works will take place Monday to Saturday during daylight hours.
The new bridge structure will be constructed on the downstream side of the existing 'Old Mandurah Traffic Bridge' using land based equipment and various marine vessels as required. Barge anchor points will be marked by lit yellow buoys, approximately one metre in height. The barge will remain on location outside of operating hours.
Closures will be in place during the works including closure of the existing downstream channel under the 'Old Mandurah Traffic Bridge'.
Alternative navigable channels upstream and downstream will be maintained and clearly marked. Mariners are advised the alternate upstream span will have a reduced width of 7.2 metres and larger vessels should consider using the Port Mandurah Canals.

Notice 2011-98: Commercial fisheries, Mandurah to Geraldton
Mariners are advised that commercial fisheries for rock lobster and octopus are established in Western Australian coastal waters, along the coast from Bunbury to the Pilbara and from shore to the 200 metre isobath with areas of high activity between Mandurah and Geraldton, particularly in the region Cervantes to Dongara.
Fishing is done using pots or traps sitting on the seabed. Each fishery contains in excess of 30,000 pots which are marked by floats not less than 200 mm in diameter and coloured, usually fluorescent green.
The floats are located on either end of a line of pots or on each individual trap. As the floats are small and unlit, a good lookout is essential when transiting the region. The fishery is active throughout the year with operations conducted by licensed support vessels. Operators monitor Marine VHF Radio frequencies 74 and 78.
Mariners are advised to navigate with caution when navigating in WA coastal waters to keep well clear of all fishing operations at all times.
