The only white tigers in Australia are ones in zoos. Australia
has no native felids at all, and tigers are found only in Asia.
White tigers are individuals of the Bengal tiger subspecies that
have a genetic condition called leucism. They are not Siberian
tigers, not albino, and not a unique species or subspecies - these
are all common mistakes people make regarding them. In the wild,
they rarely occur as leucism is passed on by recessive genes, and a
white animal sticks out like a sore thumb, but when they do it is
obviously in the areas that Bengal tigers live, such as India,
Bangladesh and Nepal. They are much more common in captivity
because people have bred them on purpose - often through
inbreeding, meaning many captive white tigers have genetic
defects.
