This is an Golden Orb Web Spider - and it is as large as it looks! The body is about the size of a normal grape - and they were reasonably common on Lord Howe. Thankfully, most of the paths on the island are walked often enough that you don't encounter these at face height when walking! (Trust me, I was thankful for that!)
