Lisa Hill and Ryan Thipthorp are in for a real workout in this episode of Fishing Western Australia, as they fish the deep waters of the Rottnest Trench for big bottom species like Bass Grouper and Hapuka. Often likened to an underwater Grand Canyon, the Rottnest Trench offers perfect fishing topography just off the coast of Perth. Ryan and Lisa tie on some massive bottom baits and get ready to hook into one of these deep-water monsters, many of which grow to over 30 kilos. If you’re looking for big, beautiful sport fishing in sunshine and good company, Western Australia is certainly the place.
