Nice work PCV. I remember doing that walk with the family in one of those brief gaps between lockdowns. Only one steep bit if I remember, with a toilet not far after the top if going anticlockwise (well planned amenities!), and the day we did it wasn't too warm.
I bought a new overnight trekking pack. I might go the Grampians or the Prom. and try it out before it becomes hot , dry , fly blown and crowded with people at these places.
