The Robinson family reports that American Jack Carter Rhoad and brothers Jake and Callum Robinson from Perth went on a surf excursion on Saturday and haven’t been seen since.
Authorities have located abandoned tents, a car, and a phone associated with the missing foreigners.
There’s a search going on along the northwest coast of Mexico.
The tourists were last seen close to a well-liked camping area in Punta San Jose, which is close to the port city of Ensenada, according to reports from the local media.
In a Facebook post on Thursday, Debra Robinson expressed concern over their disappearance and asked for information on her whereabouts.
After their camping weekend, they were supposed to check into an Airbnb in Rosarito, but they never showed up, she wrote.
“Callum is a type one diabetic so there is also a medical concern,” she stated.
