Sam won worldwide attention after she was photographed drinking from a firefighter's water bottle.
A caretaker at the rescue shelter that took her in says the furry survivor has won the affection of "Bob," another koala whose paws were also scorched in the weekend's inferno.
Lynn Raymond says Bob is Sam's protector and that "it really looks like he's making sure she's OK."
Sam and her rescuer, David Tree, were reunited at the shelter yesterday, a meeting that left the 44-year-old firefighter fighting back tears.
Neither koala is likely to be healthy enough for release for at least four months.
