The Shire of Esperance have officially begun installing the new Beach Emergency Numbers, implemented by the state government, across 575 kilometres of coastline.
The initiative has seen signs with unique codes installed at the region's most popular beaches, including Twilight Beach and the Esperance foreshore, in a bid to improve emergency response times.
The Esperance Shire Council accepted a signage grant from the state government to install the 99 signs in September 2018 - the longest coastline of any area eligible for sign funding.
The remaining signs are expected to be installed by a number of agencies, including Southern Ports Authority, the Department of Transport and the Department of Biodiversity, Conservation and Attractions, in the coming weeks.
Fisheries Minister Dave Kelly said the new signs along the state's coast were proving vital for first responders in getting to emergency situations.
"From surfing injuries to shark bites, BEN signs can help cut response times to emergencies," he said.
"No matter what the emergency is, getting the right help sooner is vital.
"It's great to see local governments working with the state government to install these lifesaving signs which now extend to the Esperance region."
The initiative was launched by the brother of shark attack victim Rick Gerring, who lost his life in 2016.
