What changed in the Federal Excise Act 2005 on 2019-03-11
Between the version published 2017-07-01 and the one published 2019-03-11, 1 section appeared for the first time.
Reading this in plain terms: a section appearing for the first time usually means Parliament inserted a new provision. A section disappearing usually means it was omitted. Neither is certain from the text alone, so treat this as a guide to what to check rather than as proof.
