Anne Cameron, 79, was reported missing on Tuesday from a nursing home near the Queensland town of Port Douglas. Police are searching for this missing woman and say she is likely to have been killed in a crocodile attack.
This idea comes from the clothes and walking stick (bearing Ms Cameron's name, who suffers from dementia) found next to a creek.
Police said on Friday that remains found nearby had been confirmed as human and were "highly likely" to belong to Ms Cameron.
"We strongly suspect now that there has been involvement of a crocodile attack," said Acting Inspector Ed Lukin.
"There will be forensic tests done on those remains, but I will stress that there are no other missing persons in the Port Douglas area."
Police suspect that Ms Cameron was attacked after walking to a bushland about 2km from the nursing home. According to local media, she had recently moved to a nursing home closer to relatives.
Wildlife officers will be setting up crocodile traps in the area where the remains were found.
