Expert in Australian land snails (Gastropoda:Pulmonata), especially Tasmanian and Victorian. Also interested in (and skilled at identifying) Tasmanian orchids, millipedes, centipedes and some beetle groups and Archaeognatha (bristletails), as well as marine Cypraeidae (cowries) from anywhere. Honorary Curator, Tasmanian Museum and Art Gallery.

Advice to people posting images of Australian land snails:

1. Don't use suggested IDs, they are often from the wrong continent. If you don't know, ID it as Gastropods.
2. Photograph the snail from multiple directions. Especially, for some common species a view of the underside of the shell is essential for identification.
3. Don't obscure location unless you don't want people knowing where you were, or unless the species is a very large snail that might be at risk from the pet trade. If a species is identified as threatened or near threatened, the site will automatically obscure it.
4.Most people struggle with estimating the size of small objects. If you have a ruler handy, measuring the shell width can be useful information to help with an ID.

NB If I only ID your snail to family, I may come back and ID it to genus or species later! For snails from NSW and Qld especially, you may get a more precise ID faster by posting on Snails of Australia facebook page.

Usual ID sources outside Tas/Vic are Stanisic et al (2010) for Qld/NSW/ACT and Stanisic et al (2018) for SA/WA/NT, accompanied by cautious use of ALA records to check distributions.
