Each time you fly into Australia, you
will find long queues at the airports' quarantine sections.
Sometimes, it could take you over an hour to get through that.
You keep wondering why they care so much for the wooden buttons on
your expensive coat or if you have absent-mindedly
left half an apple in your bag and forgotten to declare it. Other
island nations, much smaller in size, have little problems with seeds
or nuts in your luggage.
It was not always like that. In the
initial years after its discovery, the early European settlers
brought to Australia everything from cows, sheep, camels, dogs and
pigs to flowers and seeds to Chinese labourers (they did not want
brown or black slaves). With them, they brought in a whole new set of
germs, infections and diseases that the Aborigines had never
encountered in their thousands of years of existence. Then in 1859, a
man named Thomas Austin, a landowner in Winchelsea, Victoria,
imported 24 wild rabbits from England and released them into the bush
for sport. That rabbits breed rapidly is a well-known fact. Within a
couple of years, they had entirely overrun Austin's property and were
spreading into neighbouring districts.
Fifty million years of isolation had
left Australia without a single predator or parasite able to even
recognise rabbits and so they proliferated. By 1880, they had picked
clean two million acres of Victoria and were pushing into South
Australia and New South Wales. They fell onto the native emu bush
(which used to grow seven feet tall with flowers) like locusts,
devouring every bit of it – leaves, flowers, bark and stems –
until none was to be found. They ate so much that sheep and livestock
had to look for other grazing grounds, punishing wilder expanses. In
the 1890s, Australia suffered a decade-long drought. As the topsoil –
the thinnest in the world – blew away, never to be replenished,
more than half the total of the nation's sheep perished.
It took over a century since Thomas
Austin released his 24 wild rabbits for science to come up with a
solution in the form of the myxoma virus from South America. Harmless
to humans and other animals, it killed 99.9 per cent of the rabbits.
Those that survived, were naturally resistant to the virus and passed
on their resistant genes to future generations of rabbits. The
numbers were up again and are still climbing. The damage to the
landscape is irreversible. Spare a thought for the Quarantine, while you wait in the serpentine queue. It is the nation's way of
stopping the Thomas Austins.
