In part 4 of Australia, James leads and with Fraser, explores five of Australia's most dangerous spiders. These include the redback and funnel web. Another great episode and the penultimate one in the Australia series. With one more episode to go in this series could spiders be Australia's most dangerous thing or is there one more that can trump it. #australianspiders #sydneyfunnelweb #redbackspider #huntsmanspider
