Australian authorities say they are continuing to provide assistance to the family of a WA man missing in Mexico for six weeks.

Jesse Bruzzese’s last known location was Riviera Maya in Cancun but he has not been in contact with loved ones since June 3.

The 35-year-old’s disappearance remains unsolved despite being listed with Interpol and a public awareness campaign instigated by his family late last month.

His family, based in Mandurah, have opted against speaking further about their missing relative.

He was living in Perth but grew up in Mandurah and had been travelling on his own for about nine months, arriving in Mexico in early May.

Following his disappearance, the Department of Foreign Affairs and Trade has provided assistance to his family.

“The Department of Foreign Affairs and Trade is providing consular assistance to the family of an Australian reported missing in Mexico,” a spokesperson said.

“Owing to our privacy obligations we are unable to provide further comment.”

A multi-agency cross-border investigation into his whereabouts is underway, including an Interpol Yellow Notice which is used in global cases of missing people.

The notice states a list of countries Mr Bruzzese is likely to have visited: Cambodia, Mexico, United States, Thailand, Singapore, Hong Kong, China and Indonesia.

He is understood to be an experienced traveller and not one to go long without contacting family or friends.

Anyone who may have seen Mr Bruzzese, spoken with him, stayed at the same accommodation, or has any information about his whereabouts since June 3 should contact police.

His concerning disappearance has come a little over two years after Perth brothers Jake and Callum Robinson were killed in Mexico.

Authorities later concluded the brothers, along with their American friend Carter Rhoad, were killed during a robbery after they were ambushed and shot by thugs trying to steal the pick-up truck they were driving.

Their bodies were later found callously dumped in a 15m well in Baja California.
