THE QUARANTINE ACT (1908) AND AMENDMENTS is the legal base for
quarantine in Australia. Australia’s quarantine function is delivered by:
Australian Quarantine and Inspection Service (AQIS) which undertakes
quarantine operations and ensures compliance with quarantine policy. Prohibited
imports include insects and products on, or in which they might be carried. Soil is a
prohibited import.
Biosecurity Australia which develops quarantine policy and advises the
Government. Biosecurity has a plan of action if pests enter Australia.

SOME INSECTS DO NOT FLY VERY FAR, SOME ARE WINGLESS
One of their main methods of spread of such pests is by the movement of
infested plant material and they are often re-introduced into glasshouses
and nurseries by this means, eg on cuttings, in soil, vehicles, clothes many insects may
be found on clothes, shoes, vehicles, containers.
Azalea leafminer moths can only fly about 1 meter.
Mealybugs and mites crawl.
Adult female scales which are stationary.
Isolate new introductions until pest-freedom is assured.
There is no legislation to control this level of quarantine.
