Happy Bunny is checking out Darwin Harbour, near GC2EWNB (there's a photo there as well).
Darwin harbour is around 1,000km square, and has some of the highest tidal changes in the world. The trees you can see in the background are mangrove trees which grow right in the salt water. At high tide, younger trees are completely submerged. At low tide, the roots are exposed.
Darwin Harbour is surrounded by around 20,000 hectares of mangroves, the largest in the Northern Territory. The mangroves are also home to many crocodiles, so Happy Bunny won't be going there!
