While Tony Abbott is weathering a storm inside his government, one enterprising man is hoping to cash in on a controversial item associated with the Prime Minister's rise to power.

The infamous "Ditch the Witch" placard that was used in a 2011 rally against the carbon tax, and was pointed to by Mr Abbott's critics to claim the then opposition leader was sexist, has been put up for sale.

"Peter", from Lugarno in southern Sydney, has been trying to sell the item since January 2014. The asking price is now $499 on Trading Post and a whopping $3000 on Gumtree - although offers over $1000 will be considered.

When contacted by Fairfax Media, Peter confirmed it was indeed the "successful" sign that was used in many rallies at the time.
