This may be a juvenile Mysticarion insuetus Iredale, 1941 Family Helicarionidae but a bit hard to say as it's a juvenile. It is not Mysticarion porrectus. Mysticarion insuetus Iredale, 1941 ranges from Picton just south of Sydney north to the Macleay Valley west of Kempsey. It is generally found at lower altitudes compared to M. porrectus and in drier rainforest and vine thicket types. Could this be posted on 'Snails of Australia' Facebook group so that others may comment ?
