Quarantine within Australia successfully manages to prevent disease entering the country and also preventing the spread of disease across boarders.
*Controlling spread:
- if a disease is located within an area of australia quarantine sets up perimeters to ensure the disease does not spread from this location.
- For example in the combat against fruit fly measures have been implemented to ensure fruit does not move across state boarders. Due to this precaution NSW, Tasmania and the Northern Territory do not have the damaging pest.
-Thus it is clear quarantine successfully ensures diseases/ pests do not spread in between states by setting up strict perimeters and surveillance
*Preventing diseases from entering Australia:
- quarantine successfully monitors imports and exports as well as tourists/ migrants to ensure disease from across the world does not enter australia
- some of these measures include destroying foreign animal and plant products if they do not comply with the law or keeping them in isolation. Heat scanners have also been employed to detect any tourists/ migrants with a disease so that appropriate action may be taken.
- due to these precautions diseases such as foot and mouth disease and mad cow disease have not been identified within australia.
- thus quarantine through its strict measures successfully ensures foreign diseases do not enter the country
Therefore in regards to its roles quarantine is successful in limiting the spread of disease within australia and preventing new diseases from entering the country
