The large mountain under the rainbow is Mount Coramba which is nor-west of Coffs Harbour on the NSW north coast. It is 576 metres above sea level and located in the Orara East State Forest. It sits as a sentinel over the coastal strip where most of the residential areas and some farming lands are located.
The area in the front of the photograph is part of Moonee Beach Nature Reserve which is full of banksia trees and she-oaks, the South Pacific Ocean is only a short walk to the east. This rainbow lasted for 20 minutes and grew brighter and brighter, shifting till the small hill became ablaze with light. I started to imagine it was a space ship portal and imagined them running around saying, ‘On no! there’s a glitch and the humans can see us!’
