“…The Australian Quarantine Act of 1908 is a good example. The Act aimed to 'provide measures for the inspection, exclusion, detention, observation, segregation, isolation, protection, treatmen~, sanit~ry regulation and disinfection of vessels, installations, persons, goods, things, animals or plants and having as their object the prevention ofthe introduction or spread ofdiseases or pests affecting human beings, animals and plants' (Tanner and Nunn, 1998). However, although the means to regulate imports were available, prior to the 1950's quarantine of plants, both in agriculture and forestry, was very poor (Empire Forestry Association, 1948a ' Eldridge and Simpson, 1987;Walker, 1987;Wylie: 1989;Old and Dudzinski, 1998).…”
