the only existing tool that i’m aware of that will sort of handle your request is @kildor’s Missing Species tool.
your exsting query will compare taxa from verifiable animal observations at species level from South Australia against any of your observed taxa from anywhere.
kildor’s tool can’t get you exactly that, but it can compare species from verifiable animal observations at species level and lower from South Australia against species from verifiable animal observations at species level and lower from South Australia by you and another user.
if you want to get something closer to what your existing query does, it’s possible to do this by getting two lists of taxa and then comparing those, but it’s a little less automated (unless you write your own script or tool to do the comparison).
