The sentence was announced on Friday, Mexico time, one week after Jesús Gerardo (also known as "El Kekas"), Irineo Francisco and Ángel Jesús were found guilty of aggravated homicide and related offences. The men's full names were withheld by the court for legal reasons.
A translated statement from the attorney-general's office said the sentence comprised 135 years for aggravated homicide; 10 years and nine months for aggravated robbery involving violence; and 13 years for the violent theft of a vehicle.
The three victims were killed during a surfing trip in Mexico's Baja California region in April 2024. Jake, 31, a doctor due to start a new job at a Geelong hospital, had travelled to California to see his brother Callum, 32, a lacrosse player who had moved to the United States to pursue the sport, before the pair travelled south into Mexico.
Families and friends reported the men missing after they failed to check into their accommodation. Their bodies were later found at the bottom of a well along Mexico's Pacific coast.
The prosecution told the trial the murders occurred during a robbery gone wrong. The defence argued there was not enough evidence to prove the case.
The Robinson brothers' parents attended every day of the trial and were present last week when the men were found guilty. The sentencing marks the end of a lengthy legal process over the killings.
