If you have the Kinglake roof top map and head into that area, I can't remember which creek crossing it is (there's only a few right near each other), one of them is a pretty steep and long climb out. If It's wet you'll be 100% winching all day as It's slippery, steep and rutted so if your Patrol is well set up then that would be a challenge but allow a couple of hours if It's wet that's for sure.
