BRAZILIAN police are expected to access CCTV footage today in a bid to learn what happened to a missing Hobart man.

Rye Hunt disappeared from the Rio de Janeiro’s Tom Jobim International Airport on Saturday and his family are increasingly concerned.

The 25-year-old, who attended New Town High and Rosny College, was on a six-month trip of lifetime when he disappeared without a trace.

He was travelling with a mate from Western Australia, where he’d been working for the past three years.

Mr Hunt’s girlfriend Bonnie Cuthbert said she believed Rio police would today view cameras from the airport where her partner was last seen.

Mr Hunt and his travelling companion were planning on flying to Bolivia the day he went missing.

The pair split up for about 30 minutes at the airport to grab a coffee but Mr Hunt never returned to their agreed meeting point, which was also within the airport.

Ms Cuthbert last spoke to her partner on Friday, May 20, and said there was nothing unusual about the call.

Mr Hunt’s sister Romany Brodribb said her brother had not accessed his bank accounts since he went missing.

Family members plan to fly to Brazil to help in the search.

He is described as being 175cm tall, weighs 98kg and has a tanned complexion and dark brown hair.

His family, who are planning on flying to Rio, are liaising with the Department of Foreign Affairs and Trade.

“The Australian Embassy in Brasilia is working closely with local authorities to locate an Australian man reported missing in Brazil,” A DFAT spokesman said.

“DFAT is providing consular assistance to the man’s family. Due to privacy obligations, we will not provide further comment.”

Tasmania Police said the matter had been reported to them.

“Tasmania Police will work with DFAT and other agencies as required,” a police spokeswoman said.
