Site Tour

A day tour is being organised for Monday July 8th at the Condong Sugar Mill and the Stone and Wood Brewery in Murwillumbah (1 hour drive south from the Gold Coast). The Condong Sugar Mill sits on the banks of the Tweed River and has been crushing cane since 1880. The Condong Sugar Mill tour will consist of a visit to a sugar cane farm and the processing mill.

Following this, a tour of the Stone and Wood facilities including some tastings of the locally brewed beer will finish off the day before heading back to the Gold Coast before the Welcome Reception. This tour will depart from the Mantra on View, Surfers Paradise at approximately 8:30 am and return at approximately 4:00 pm
