  Advice: Navigational hazard; Sand movement, navigational aids off station and unlit - Carnarvon Fascine

Mariners are advised that a large sandbar has encroached upon the Carnarvon Fascine navigational channel.

The sandbar extends in an easterly direction from the entrance port beacons and can vary in size and position across the channel's entrance reducing depths and severely restricting navigation.

Navigation aids in this area do not indicate a navigable channel and some are unlit.  Mariners should not rely on these navigation aids for safe navigation.

Any attempt to navigate a vessel through the area is done so at the risk of the vessel operator.

Mariners are advised that ocean access may not be possible if launching from the Fascine boat ramp. The Carnarvon Boat Harbour boat ramp is open to provide an alternative option for launching vessels via Teggs Channel.
