The Liberal party has pledged to station a wildlife officer in Mandurah ahead of the state election.
The Mail earlier this week reported that local environmental groups and tourist providers were desperately calling for a dedicated wildlife officer in the region.
It follows previous reports of Mandurah dolphins left entangled in fishing line for up to six months due to a lack of resourcing and local expertise.
Volunteer groups have been lobbying the state government for the past two years and they put more heat on when much-loved Mandurah dolphin calf, Luca, died after his third fishing line entanglement.
But the plea for a local wildlife officer has thus far gone unheeded by the state government's Department of Biodiversity, Conservation and Attractions (DBCA).
On Thursday Opposition leader Zak Kirkup pledged $250,000 for a boat and jetski for shallow water monitoring as well as "at least one dedicated officer to be stationed in Mandurah either permanently or rostered on rotation".
Volunteers currently use personal boats at their own expense to monitor and help the dolphins.
Mr Kirkup said the Swan River had just 25 resident dolphins and several wildlife officers, while Mandurah had close to 90 and no locally-stationed officers.
"It's important to understand Mandurah's estuarine dolphin population doesn't breed with coastal dolphins, meaning breeding females are critical to the health of the population," Mr Kirkup said.
The Labor party has been contacted for comment.
