Origin
South-eastern Australia (Gippsland / Victoria, southern NSW)
Protection status
— (no CITES; an Australian export ban)
Brumation
A cooler overwintering of several weeks (more strongly adapted to cold)
Cohabitation
A pair or group with one male; do not cross them with the eastern subspecies. The reason: several males fight over territory and the warm spot until one is injured or spends its life in a corner. Females usually get on, but each needs its own warm spot and hide; feed them separately once they differ in size.

Notes

A more southerly subspecies, adapted to cold and more sensitive to heat – keep it a little cooler than the eastern form. It lacks the dark eye stripe; do not cross it with lesueurii.
