Stick insect like bug help (Australia Victoria)

So I found this bug and originally thought it may have been a stick insect, and as I am getting into the insect keeping hobby I put it in a terrarium, but now I’m thinking it might be something different. Help appreciated (as I am not sure how to post photos I’ll do my best to describe it, sorry if this makes it hard) it’s green and has legs which are shaped like a triangle like a cricket or grasshopper ( it can jump pretty high) and has a small thin green head in conparison to its longer, slightly thicker green body (found in Australia Victoria)
