Remains of backpacker Rye Hunt due home in Tasmania

The remains of backpacker Rye Hunt, who died while travelling in Brazil, are expected to be returned to his Hobart home this weekend.

The 25-year-old's body was found washed ashore at Marica near Rio de Janeiro on June 8 following a desperate search after his disappearance 18 days earlier.

Brazilian authorities believe Mr Hunt may have died from dehydration or drowning after attempting to swim while under the influence of recreational drugs.

His uncle Michael Wholohan and girlfriend Bonnie Cuthbert are expected to arrive back in Hobart with his ashes some time on Saturday or Sunday.
