Mt Hay and Kolong Ridge circuit

Just read a post from Phil S from a few years ago planning a trip from Mt Hay- Boorong Crags - Mt Hay Range - Moogan Gulley - Kolong Ridge - Hurley Heights spur-back along fire trail. It sounds good to me, maybe with a camp on Kolong Ridge, but don't know area and it seems Phil's not been on this site for a few years. Has anyone done this? If so, what's it like to cross Mt Hay Creek from south end of Kolong Ridge to Hurley Heights? Do-able or too cliffy? How about the rest of the circuit - any tips/tricks/difficulties?
