Martin Robinson held his wife Debra as she addressed the court on the final day of the murder trial, saying "our lives will never be the same without them, but our love for them will never fade".
"Callum and Jake were our only children," Debra Robinson said. "Their loss has taken from us not only the sons we loved, but the future we imagined with them. The day Callum and Jake were murdered, our world stopped ... We never want another family to experience the devastation and suffering that has been inflicted on ours."
The Robinsons have attended every day of the trial in Ensenada, on Mexico's Pacific Coast, which began in early September. After five weeks of proceedings, judge Raúl Hernández Arellano is set to rule on the guilt of the three accused murderers on Friday afternoon, Mexico time.
The parents have asked that the three men never be released. The killings of the brothers, which occurred while they were surf touring in Mexico, drew widespread attention in Australia and overseas.
