Systematic illustration of an ocarina with Standard Australian fingering system.

Unglazed prototype of a Panch Ocarina of Time replica with a Simplified Australian fingering system.
The Australian fingering system was invented by Panch Sheehan. It is based on the English fingering system, with extra holes on the left hand to extend the range. The idea was inspired by the design of the fictional Ocarina of Time. A notable property of this design is that it is in mirrored sweet potato form, just like the ocarina of time.
