On 22 October Sir Peter Cosgrove was presented by Ambassador Hugo Gobbi with a diploma corresponding to the Order of the Liberator General San Martin. The former Governor-General was invested with the insignia of the Collar of the Order of the Liberator General San Martin on his visit to Argentina in 2016, in recognition of his efforts to strengthen the bonds of friendship between Argentina and Australia.

Among his many accomplishments, the former Governor General was the first Australian Head of State to honour Argentina with an official visit.
