More than 50 vessels were waiting to be loaded at Port Waratah Coal Services Newcastle coal loaders at the end of November. Now there are 60 vessels, a number not seen for several years. But a vessel arrival system means only 20 ships can stay in the Newcastle anchorage, with others anchored elsewhere or in transit. But the ship queue spike is not expected to affect export targets through the Port of Newcastle. The ship queue should drop soon with the number of vessels waiting expected to be below 40 at the end of January.
