The Australian Ambassador to France, Brendan Berne, ordered flags at the embassy in Paris to be flown at half staff in Simon's honor. The small town of Robinvale, Victoria, which is twinned with Villers-Bretonneux, paid tribute to Simon, saying, "We extend our condolences to Mr Simon's family, friends, the Villers-Bretonneux community, and the Robinvale-Villers Bretonneux Association members during this sad time." Robinvale was named after Lieutenant Robin Cuttle, who was killed in action in Caix during the Second Battle of Villers-Bretonneux in 1918. Simon had visited Robinvale several times, most recently in October 2019, and developed close personal and professional relationships with the town's leaders.
