S. spectabilis is found in the Australian states of New South Wales, Queensland, South Australia and Western Australia.

[1][2] The preferred natural habitats of S. spectabilis are grassland and shrubland.

[1] Adults of S. spectabilis have an average snout-to-vent length (SVL) of 26.5 cm (10.4 in), and the length of the tail is on average 12.5% SVL.

[2] Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Parasuta.

The subspecific name, bushi, is in honor of Australian herpetologist Brian Gordon Bush (born 1947).
