‘The fish that went fly-about’ is inspired by the Australian aboriginal legend ‘The fish became the moon’.
In the time known as ‘Dreamtime’ the world took shape, the ancestors retired into the earth, into the sky, into the clouds and into the creatures, and planted in the earth, as the ancestors call it, the ‘seed power’. Every creature and every mountain and every stream and waterhole and rock and river is implanted with this seed, which gives off a vibration, and this is the Earth’s inner dreaming.
It is sacred, like so many of the Dreamtime stories. ‘The fish became the moon’ is a story about two sisters catching a fish and seeing it climb into a tree and float into the sky where it became round and slowly disappeared behind the horizon.
There are BTW different versions of this tale in Arnhems Land, East of Darwin as I discovered during 6 weeks walkabout in 1994.
