Monga National Park sits right on top of the east coast escarpment, happily collecting rain from the warm air pushed in from the coast. In the wetter parts of the park there are green rooms of tall tree ferns. In other parts the ferns retreat to a more regular layer of incandescent green undergrowth around tall, dense eucalypt forest. While I was there the clouds built and the wind picked up and you could hear the stir of the rain pushing through the forest, until it hit in a downpour of uncommon force.
