Long considered a welcome addition to the Australian environment, primarily as a highly valued hunting resource, deer populations have flourished under legislation providing for their protection. Like rabbits and foxes, all six deer species with recognised wild populations Fallow, Red, Sambar, Rusa, Hog, Chital were released into Australia for aesthetic and recreational hunting purposes during the 19th century.
History[ edit ] Rabbits were introduced to Australia by the First Fleet in In the first decades, they do not appear to have been numerous, judging from their absence from archaeological collections of early colonial food remains.
However, by in Tasmaniaa newspaper article noted " We understand, that there are no rabbits whatever in the elder colony" i. At the same time in NSW, Cunningham noted, " The first of these, in Sydney at least, was one built by Alexander Macleay at Elizabeth Bay House"a preserve or rabbit-warren, surrounded by a substantial stone wall, and well stocked with that choice game.
In — Alexander Buchanan, overseer for F. Their population remained fairly stable until aroundpresumed to have been kept in check by native carnivores and were protected by an Act of Parliament, but by was out of control. Alfred, Duke of Edinburgh, rabbit shooting at Barwon Park, Victoria in the s The current infestation appears to have originated with the release of 24 wild rabbits  by Thomas Austin for hunting purposes in Octoberon his property, Barwon Park, near Winchelsea, Victoria.
Australia pest living in England, Austin had been an avid hunter, Australia pest dedicating his weekends to rabbit shooting. Upon arriving in Australia, which had no native rabbit population, Austin asked his nephew William Austin in England to send him twelve grey rabbits, five hares, seventy-two partridges and some sparrows so he could continue his hobby in Australia by creating a local population of the species.

Pest Analysis PEST on Australia Political aspect 1. Trading policies Maintains active and diverse international trade policy agenda which combines multilateral, regional and bilateral strategies to break down world barriers to trade. Under the Australian Animal Welfare Strategy, the NSW Department of Primary Industries’ Vertebrate Pest Research Unit, has developed a model for assessing the relative humaneness of pest animal control methods.
One theory as to why the Barwon Park rabbits adapted so well to Australia is that the hybrid rabbits that resulted from the interbreeding of the two distinct types were much more suited to Australian conditions. A load of rabbit skins, Northern Tablelands, New South Wales At the time he had stated, "The introduction of a few rabbits could do little harm and might provide a touch of home, in addition to a spot of hunting", a prediction which has not aged well.
Australia had ideal conditions for a rabbit population explosion. With mild winters, rabbits were able to breed the entire year.
With widespread farming, areas that might otherwise have been scrub or woodlands were instead turned into vast areas with low vegetations, creating ideal habitats for rabbits. In a classic example of unintended consequencesrabbits had become so prevalent within ten years of their introduction in that two million could be shot or trapped annually without having any noticeable effect on the population.
It was the fastest spread ever recorded of any mammal anywhere in the world. Today, rabbits are entrenched in the southern and central areas of the country, with scattered populations in the northern deserts. Although the rabbit is a notorious pest, it proved useful to many people during the depressions of the s and s and during wartime.
Trapping rabbits helped farmers, stockmenand stationhands by providing food and extra income, and in some cases helped pay off farming debts. Rabbits were fed to working dogs and boiled to be fed to poultry.
Later, frozen rabbit carcasses were traded locally and exported. Pelts, too, were used in the fur trade and are still used in the felt-hat industry. They are suspected of being the most significant known factor in species loss in Australia. The rabbits would first deplete the natural pasture vegetation, and would then resort to consuming woody-vegetation, which included small shrubs, and the leaves and bark of trees.
The removal of this topsoil is devastating to the land, as it takes many hundreds of years to regenerate. Once the problem was understood, various control methods were tried to limit or reduce the population of rabbits in Australia. These methods had limited success until the introduction of biological control methods in the latter half of the 20th century.
Common control measures[ edit ] See also: Animal population control An old poison cart which distributed poisoned baits to kill rabbits, Woolbrook, NSW Shooting rabbits is one of the most common control methods and can successfully be used to keep already low populations in check whilst providing food for people or pets, though large scale eradication requires different means.
The sandy soil in many parts of Australia makes ripping and ploughing a viable method of control, and both tractors and bulldozers are used for this operation. Poisoning is probably the most widely used of the conventional techniques, as it requires the least effort, and capable of destroying a local population, though of course re-infestation by the highly mobile pest is almost inevitable.
Laying baits of pollard laced with a phosphorus -based poison, such as "S.Marine pests threaten Australia's unique marine environment and marine industries.

Prickly pears (Genus Opuntia) are an invasive plant species in Australia.. Prickly pears (mostly Opuntia stricta) were imported into Australia in the 19th century for use as a natural agricultural fence and in an attempt to establish a cochineal dye industry.
Many of these, especially the Tiger Pear, quickly became widespread invasive species, rendering 40, km 2 (15, sq mi) of farming. Various programs exist to control invasive species in Australia.
A cane toad control program aims at preventing the spread of the species towards Darwin and Western Australia, and involves trapping.
