Migaloo was sighted by Silversonic swimming north of Undine Cay at 9.30am this morning. Silversonic was on route to Agincourt reef when this rarly seen whale was sighted for the first time in Port Douglas. The extremely delighted passengers and crew on Silversonic cruise were in awe of the rarely seen white humpback whale, Migaloo. This is the third year in a row the Quicksilver Group has been the first to sight Migaloo. Last year he was first sighted off Green Island on the 15th July and in 2005 off Low Isles on the 16th July.
