While the ALA goes to considerable effort to aggregate available information about all Australian species, there are some circumstances in which the ALA may not display information about a species you are interested in. These include:
- the species name may have changed
- the species is not listed in any of the sources of the ALA's species names, e.g. it may be newly described, or the name is a manuscript or phrase name
- the spelling used may be different from that officially recognised, though the ALA tries to include misspelled names, synonyms and homonyms
- the common name used may not be recognised by the ALA.
