I reckon you must be in either category A or B, and I'm in either D , E
or F.

Instead of one list, one could adopt that used in the UK and adopted by
Hong Kong:
Category A    Species which have been recorded in an apparently wild
state in Australia within the last fifty years,
Category B    Species which have been recorded in an apparently wild
state in the UK, but not within the last fifty years. ( ie Dr Death)
Category C    Species which, although originally introduced by man, have
now established a regular feral breeding stock which may or may not be
self-supporting. ( ie John Howard)
Category D     Species which have occurred in an apparently wild state
but for which the possibility of escape or release from captivity cannot
be satisfactorily excluded.
Category E    Species for which all published records are suspected of
being  escapes or  released from captivity.
Category F     Species for which all published records must be regarded
as doubtful because of the possibility of mistaken identity.
