This flight plan takes in 32 national parks in the Australian state of New South Wales. It is 667 nautical miles in length. For your planning purposes, the route took about five hours in the CubCrafter, but I've added a few stops if you want to break it up over a couple of sessions. I added Katoomba Airfield (RIP, Rod Hay) early on for a touch and go, since it's a great little location above the township. Another touch-and-go, near the end, is Nobby Creek (YNOB) (freeware).

We depart from Mittagong (YMIG) (freeware), due east of Wollongong, with an elevation of 1,399 feet. Our arrival airport is Tyagarah (YTYH) (freeware).
