At Cowombat, peel off towards the east on the MacFarlanes Flat FT, then head south up a long open grassy lead a little west of *
Mountain Trout Creek. This will get you to a very obvious brumby pad that climbs up through the trees onto the higher country a bit east of Cobberas2's plateau. You then head SW, connecting the open ground. A few boggy bits but mostly pretty good going. Try to keep away from the obvious crags, they're a *&%$#! to climb with a full pack. I sidled a few to the south but it might be easier to keep north of them by heading SW further north.
(I was going in the opposite direction, but the route is still good.)
Once you're up on the northern plateau, it's easy going except for a minor scramble down from the rocks to the open grassy snowgum section that leads towards the rocks at the Cobberas 2 high point, which is at the southern end.
Moscow is a short sidetrip, best done from approx SE of the summit. You can go up directly from the north, but it's much harder work and again there are some awkwardly placed crags to avoid. After climbing Cobberas 1, continue SW on some very obvious brumby pads until you reach an open rocky lookout just north of where Bulley Creek rises. (I think it's Bulley . . .
edit: no it isn't, it's Stony Creek. ) , then peel off on the most obvious pad to join the track on the creek flats. This is very close to where the AAWT leaves the Cowombat FT.
(Green dots are, from right to left, Cobberas 1, where you leave the pad to the Playground, where you rejoin my route, and where you hit the fire trail. This specific loop was just a two dayer from the Playground.)
I can send you the GPX file if required.
*edit: Apparently, despite one map saying so, the creek I'm thinking of isn't Mountain Trout Creek. No matter, it's the first major creekline running north into the flat on the eastern side of the fire trail. You follow the longer, more open lead that is just west of it. I think the images make it clear where you go. Apologies for the stuff up on names.
