Hughes, who played 26 Tests, died from bleeding in the brain on November 27 last year after being hit on the base of the skull by a rising ball at the Sydney Cricket Ground during a domestic match.
His death, a freak accident, stunned Australia and the world cricket community, sparking an outpouring of grief.
While Cricket Australia immediately boosted the medical presence at grounds and now requires all players to wear a helmet that meets certain safety standards, Hughes' long-time coach and mentor Neil D'Costa said he was still not convinced it was enough.
"Safety is our absolute top priority and I'm not sure we're doing everything humanly possible to honour Phillip's memory," he said.
"You can erect plaques and that's all nice but when it's said and done, are we doing everything we can to make sure it doesn't happen again to someone's child?” added D'Costa.
