The NSW Nationals and Liberals are calling for an end to measures designed to ensure marine conservation along the state’s coastline.

Nationals MPs Andrew Stoner and Duncan Gay are spearheading the campaign to halt the creation of any more marine parks in NSW.

The parks are designated areas of coastline set aside for management by the Marine Parks Authority.

Traditionally around one fifth of these parks are no-go zones for any extractive activities like fishing, and it’s these sanctuaries that the Opposition is worried about.

They say the Government is denying locals their right to enjoy the great outdoors.

But environmental groups have slammed the Coalition’s vision, saying marine parks and sanctuaries are crucial to ensuring the health of our oceans.
