Some of missing Australian man Rye Hunt's belongings have been found more than a week after he disappeared from Rio de Janeiro's main airport.
The 25-year-old left Galeao International Airport in a taxi on May 21, after arranging to meet his travelling companion again in 30 minutes, his family said in a statement on Sunday.
Some of Mr Hunt's personal effects have been found but their location has not been released.
Mr Hunt and his travelling companion, who he had spent seven weeks travelling through Southeast Asia and South America with, were captured on CCTV before they split up.

"There appears to have been an argument between Rye and his travel partner in the airport," the statement said.
A crowd-funding campaign has raised money to send Mr Hunt's uncle and his girlfriend to Rio to coordinate the search.
The brother of his travel companion will also go to offer support.
"Receiving information today has given us, sort of, renewed hope," Mr Hunt's sister Romany Brodribb told ABC Radio.
"It better informs where the search will progress to from here."
Tasmanian and West Australian police have been working with DFAT and Brazilian authorities to find Mr Hunt, who has not used his social media, email and bank accounts, and doesn't appear to have used his phone.
Mr Hunt grew up in Tasmania and had been working in Kalgoorlie until he left the country on April 1.
He is an experienced traveller having also visited Southeast Asia and New Zealand.
A social media campaign to #findrye has been shared across Australia and South America.
