Can I buy Green Sands beverage in Canberra?

I had a hard time finding info. on this drink. I would suggest contacting the director of the festival to find out the name of the vendor who supplied the drink to find out how they were able to get it. You may also ask your local liquor store to see if they could purchase some for you. You may have to buy a large quantity of it, but at least it would keep you good on it for a while.
