There is pink tape at regular enough intervals and, though the area was burned, there is not the super-thick regrowth that we encountered on the far side of the ridge the previous day. The tree is very difficult to access via the East...we turned back after a few hundred metres of bushbashing took us over an hour.
The tree itself seems to be living well enough but is fire affected. There are classic 'cathedral arches' around it and several people could fit inside the tree...there are several points along the lower trunk where holes seemed to have burned through letting light into the cavity at its base.
Given the length and condition of the walk via your route, I would say any uninjured person of a reasonable age could do it without navigation aid- though I would recommend an appropriately equipped first aid kit (we had plenty of both).
