Last week, Ms Dixon called for the grating type on the boardwalk to be changed, so snakes could not climb through or for council to remove the boardwalk completely.
The council responded by filling the grates with sand.
Issues with the boardwalk came to a head after a number of residents posted images on social media of venomous snakes inside the grating.
Ms Dixon said the five dugites spotted under the boardwalk were mating.
“They have a boardwalk that the developer put in there to aesthetically entice people to Seascapes,” Ms Dixon said.
“This is regardless of what jeopardy you’re putting residents in.
Ms Dixon said she had 18 phone calls in relation to the boardwalk at the weekend.
She wants warning signs to be installed at snake hot spots in multiple languages.
Ms Dixon said 15 dogs had been killed by snakebites at Seascapes Beach in the past few years.
A representative of the City of Mandurah did not comment on the request for signage but said they would be removing bushland from around fences, creating a buffer zone.
