This is one of several species of large, aggressive spiders, which are found in the warmer and more arid regions of Australia. Some species are known as barking or whistling spiders because of the sounds they can produce by rubbing their palps (the appendages between the front legs) along a set of spines at the base of their fangs.
if that's not enough, our australian tarantulas are less passive than other versions. sometimes a hunstman spider will come into the house and look around - one crawled into my bedroom earlier in the year and i slept on the couch in the lounge room for three weeks.
