This has to be the biggest spider I've ever seen in the Kimberley. An Australian Tarantula. Can have a leg span of up to 16cm. What a beauty!
Australian tarantulas are non-aggressive, but if provoked can inflict a painful bite. An adult’s fangs can be 1cm long. Australian tarantulas mainly eat other spiders, insects, frogs and lizards. Female tarantulas may live up to 12 years and spend most of her life in her burrow. ~ https://www.spiders.com.au/australian-tarantula-spider.html
