Bushwalk Australia

Has anybody tried climbing up Mt Sedgwick from Lake Margaret? I plan to go there soon, on an overnight trip, camping at Lake Adam. There looks to be a bit of scrub on the map on the main ridge up towards and over Sedgwick Bluff. Google Earth shows a fair bit of rock however. An alternative might be to walk eastwards around the shore of Lake Margaret, and then bash uphill more directly towards Lake Adam.

I have now reposted this question in the Tasmania section. Apologies.
