Fans of the Cardrona Bra Fence are being called upon to donate their pre-loved bras in an effort to re-stock the controversial tourist attraction.

Photos have emerged on social media of two women cutting the bras off the fence.

The action has angered locals, with a 50-dollar bar tab offered to anyone who would "dob" the women in.

A post on the Cardrona Bra Fence Facebook page asks people to send in their second hand bras, with a community day to be held where all the bras are re-hung.
