Travel by Danielle Gusmaroli Premium Content Subscriber only Desperate Christmas holiday-makers banned from the golden sands of Queensland are piling onto the beaches of Byron Bay, which have been shrunk by coastal erosion and cyclonic storms. As workmen toil to repair the shoreline, at a cost of millions of dollars, and with state borders shut to Greater Sydney and the Central Coast, Sydneysiders have converged on the coastal town, where the seashore has been reduced to a debris-strewn slither. Trucks ferrying 700 cubic metres of sand from Pottsville, 35km north of Byron, are arriving to shore up Clarke's Beach, which was battered again by last week's rains and high tides, in an operation costing $1.5 million.
