An upgrade of navigation aids on Rottnest will allow skippers to travel more safely to and from the island at night.
As part of the project, 23 navigational aids at the island's busiest locations have been lit to define navigational channels at night.
The Department of Transport's acting marine operations director Ray Buchholz said the $70,000 project was part of the continuing upgrade of the 1400 navigational aids around WA.
"While the upgraded markers will provide safer access for all vessels navigating after dark around Rottnest, the boating community must continue to be aware of the additional dangers when navigating at night," Mr Buchholz said.
New markers have also been installed at the entrance to Herring Bay at Garden Island.
