Cape Town - Barbarians coach Alan Jones hit out at New Zealand referee Brendon Pickerill after his side lost 31-28 to the Wallabies in Sydney on Saturday.
Australia trailed for most of the match and found themselves four points down heading into the final 10 minutes, before two Barbarians yellow cards in quick succession gave the hosts a two-man advantage.
Wing Taqele Naiyaravoro, having scored a double, was yellow-carded for repeated offside infringements.
He was joined in the sin-bin a few minutes later by Barbarians captain Quade Cooper, who executed a high tackle on Israel Folau.
Jones, who was head coach of the Wallabies in the 1980s, was not happy with the refereeing and also hit out at the administrators of the Australian Rugby Union.
