It is quite possible that it even arrived with the Macassan traders several hundred years earlier. It has since spread throughout Australia, particularly in the south of the continent. to Australia There is also an apparent correlation between the canopy height and logs and the presence of black rats.

Our largest is the water rat (Hydromys chrysogaster), which can weigh more than 1kg. They vary in size from the pygmy possum, weighing just 7 grams (14oz), to the cat-sized common ringtail and brushtail possums. They weren't actually deliberately introduced but rather came In a study in New South Wales, Australia it was found that, although the bush rat consumes a diversity of truffle species, the black rat consumes as much of the diverse fungi as the natives and is an effective vector for spore dispersal. Rats are deeply integrated into almost every human settlement. By eradicating the black rat populations in Australia, the diversity of fungi would decline, potentially doing more harm than good.

[7] When Europeans settled Australia they intentionally released many species into the wild, including the red fox, brown hare, and the European rabbit. Although the black rat was certainly a plague vector in European ports, the spread of the plague beyond areas colonized by rats suggests that the plague was also circulated by humans after reaching Europe.

When the abundances of these two rat species were compared in different micro-habitats, both were found to be affected by micro-habitat disturbances, but the black rat was most abundant in areas of high disturbance; this indicates it has a better dispersal ability. As found in North Head, New South Wales, there is positive correlation between rat abundance, leaf litter cover, canopy height, and litter depth.
