Are there giant spiders in Australia?
Huntsman spider
More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas.[4]
Great raft spider
The spider was first found in South Wales in 2003 in the disused Tennant Canal at Pant-y-Sais Fen. Surveying found a stable population as well as identifying further occurrences at the nearby Crymlyn Bog and in connecting wetlands but the full range of the spider is not fully known. This due to the difficulty of surveying work in wetland terrain and problems with identification. The habitat at the site is considered good enough for the population not to be declining.
