In 1984 a shotgun was banned from import: This was the first time a long gun was banned under the "sporting purposes" clause of the GCA 1968. In 1986 another shotgun was banned from import. In 1989 over 40 semi-automatic guns were banned form import. In 1998 more "assault weapons" were banned form import under the "sporting purposes" clause of the GCA 1968.
