Madang
Also in PNG, Madang has some great wreck diving. The Mitchell Bomber is an excellent example of a WWII plane wreck, while nearby, the USS Boston and Coral Queen are also fantastic wreck dives. A night dive on the Coral Queen is a dive with a difference, with millions of Flashlight Fish lighting up the water with their impressive show of bio-luminescence.
