I came across this cricket in WA, Australia in the bush a few years back.
Would like to know what is its name?
This is a Toxic Milkweed Grasshopper in the family Pyrgomorphidae, but we are uncertain of the species. At first we thought it might be a Blistered Grasshopper, Monistria pustulifera, which we have identified before, but the markings are different, especially the yellow band through the face on the Blistered Grasshopper. We speculated it was a different species in the same genus, which led us to a photo of a Mountain Spotted Grasshopper, Monistria concinna, on FlickR, and it looked very close, but when we checked the range on Csiro, it was wrong. We also found photos on Dave’s Garden, and they look different than your individual. So, we believe your Toxic Milkweed Grasshopper is in the genus Monistria, but we are not certain of the species. Csiro indicates several species found in Western Australia, but alas Csiro does not have photos of them. You might try writing to Csiro to see if they can identify the species, and if they do, please get back to us so that we can name this beautiful Toxic Milkweed Grasshopper more specifically.
