Info on central plateau Tassie


Hi Guys! Have never done this forum stuff before so bear with me.
Are about to start planning a trek in Tassie from about Dixon’s track near Meander Falls up to Higgs track , Ritters, across to the Walls of Jerusalem area and then on to Cradle, or something like that.
Looking at about 5 to 7 days.
Hoping someone has some info in that area, or a better plan to look around that area, time of year to do it etc etc.
Have been up Dixson a long time ago on a day hike and the landscape blew my mind.
Any info would be great.
