The ashes of Australian man Rye Hunt have returned home to Tasmania after he was cremated in Brazil.

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.

• Rye Hunt died from ‘dehydration or drowning’

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 arrived back in Hobart with his ashes on Sunday morning.

“The family spent the day with them debriefing and sharing memories of Rye,” his sister Romany Brodribb told AAP on Sunday.

“We are planning to hold a celebration of Rye’s life on July 10 in Hobart for family and friends.”
