Founding Greens party leader Bob Brown has joined the fight against a proposed sand mine in Yallingup in WA's South West.

The state's peak construction body says the local sand would be vital to the construction of housing in the region.

Public consultation on the proposed mine, facilitated by the City of Busselton, is open until June 12.

One of Australia's most prominent conservationists has joined a hyperlocal fight against a small-scale sand mine proposed in Yallingup in Western Australia's South West region.

The swimming spot's striking granite boulders and pristine water attract scores of visitors.

Aside from natural beauty, critics are also concerned about an increase in traffic on the tourist thoroughfare of Caves Road.

The mine could add another 200 heavy truck movements to Caves Road each day.

Protect Our Pits organiser Matt Mulhall said road safety was a chief concern among many.

"Unfortunately, they're quite a dangerous road already, just considering the nature of them winding their way through scenic va
