I recently saw a P. glaucus ssp. australis from Georgia for sale, is this a valid ssp.? Last I heard there was only nominate and ssp. maynardi from Florida.

No this is not a valid subspecies; and even if it was, the name Papilio australis Maynard, 1891 is a junior homonym and thus unavailable.
Also I believe that australis was described from Florida, although I haven't checked the original description. It was often used as the subspecies name for the Florida population in older literature, but maynardi Gauthier, 1984 is the correct name for that subspecies.

Recent studies show that it is a good subspecies (vide infra), but I don't think it can be found in Georgia! Yes australis is an invalid name, I hare rename this subspecies a long time ago: Papilio glaucus ssp. maynardi.
Here is the title and abstract explaining the very peculiar ability of this ssp. vs glaucus.
Salicaceae detoxification abilities in Florida tiger swallowtail butterflies (Papilio glaucus maynardi Gauthier): Novel ability or Pleistocene holdover?
by Matthew S. Lehnert & J. Mark Scriber
Abstract: Florida populations of the eastern tiger swallowtail butterfly, Papilio glaucus L., have unique morphological features and ecological adaptations that have contributed to their subspecies status (P. g. maynardi Gauthier). We describe geographically unique abilities for detoxification of Carolina willow, Salix caroliniana Michx. (Salicaceae), for several Florida populations of P. g. maynardi. Of all the approximately 570 worldwide species of the Papilionidae, such Salicaceae detoxification abilities exist only in the allopatric North American western and northernmost species (P. rutulus Lucas, P. eurymedon Lucas and P. canadensis Rothschild & Jordan). Females of P. glaucus collected from populations in southeastern USA were examined for oviposition preference in 5-choice assays, and displayed a low preference for Salicaceae (<5%), but larvae from Florida populations exhibited a high survival (>60%) on these plants. Detoxification abilities have previously shown to be autosomally inherited, and can be transferred via natural or hand-paired interspecific hybrid introgression. However, these Florida populations are at least 700–1 500 km from the nearest hybrids or the hybrid species, P. appalachiensis Pavulaan & Wright, which possess these detoxification abilities. In any case, the Z ( = X)-linked oviposition preferences for Salicaceae are lacking in these Florida populations, illustrating genetic independence of oviposition preference determination and larval survival/performance abilities. The origins of detoxification abilities are unlikely to be due to recent climate-driven introgression, and may represent ancestral trait carry-overs from interglacial refugium populations of the Pleistocene epoch.

Yes, I know that now ssp. maynardi is valid and from central/southern Florida, but I had seen an ebay listing selling ssp. australis from Georgia, so that is why I asked the question. I have checked all references and ssp. australis is not valid, only ssp. maynardi and nominate. Thanks.

I have them from Florida and Georgia,(I just don´t have now the time to check if they are from southern Georgia or to post pictures of them) and I don´t see any difference between ssp.maynardi from Florida or (southern)Georgia they are all very large and most females have a very dark yellow(more like orange)For me they are identical with Florida ssp.maynardi.
Also Papilio troilus from Southern Georgia looks like the ones from Florida(except the ssp from Southern Florida)
