Testudo australis was named by Moreno (1889). Its type specimen is MLP 26-400, a partial shell, and it is a 3D body fossil. Its type locality is Monte Hermoso, which is in a Montehermosan terrestrial siltstone in the Monte Hermoso Formation of Argentina.
It was considered a nomen dubium by Auffenberg (1974); it was recombined as Chelonoidis australis by de Broin and de la Fuente (1993), de la Fuente (1997), de la Fuente et al. (2014) and de la Fuente et al. (2018).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. S. de la Fuente et al. 2018 | Member of Testudinidae based on the following characters: presence of alternating quadrangular/octagonal neurals 2–5 with corresponding alternating costals; coincidence between the costo-peripheral suture with the pleuro-marginal sulci; well-developed axillary buttresses making contact with the costal bones viscerally; well-developed epiplastral lip. Associated with Chelonoidis gallardoi due to the development of vertebral gibbosities; differs from Ch. gallardoi in carapace proportions, the absence of pleural gibbosities, a wider epiplastral lip and a less developed anal notch. |
