Moyano missed the 35-17 loss to New Zealand last Saturday due to a rib complaint but has been drafted into the 30-man squad as a replacement for Bautista Delguy, who will be out for three weeks with a shoulder injury, the Argentine Rugby Union said in a statement.
Coach Mario Ledesma also included blindside flanker Santiago Grondona in place of the injured Tomas Lezana and winger Manuel Montero for Matias Osadczuk, who was released to play for Argentina's second string side in a tournament in Uruguay.
The Pumas host Australia in Salta on Saturday in their last Rugby Championship match of the season.
Argentina are three points ahead of Australia, who have won only one of their five matches in the competition this season and were surprisingly beaten 23-19 by the South Americans when the teams met in Queensland last month.
New Zealand wrapped up the Rugby Championship title last weekend when they beat the Pumas in Buenos Aires.

1-Matias Alemanno, 2-Gonzalo Bertranou, 3-Emiliano Boffelli, 4-Sebastian Cancelliere, 5-Agustin Creevy, 6-Tomas Cubelli, 7-Jeronimo De la Fuente, 8-Bautista Ezcurra, 9-Diego Fortuny, 10-Santiago Garcia Botta, 11-Santiago Gonzalez Iglesias, 12-Santiago Grondona, 13-Ramiro Herrera, 14-MarcosKremer, 15-Martin Landajo, 16-Tomas Lavanini, 17-Juan Manuel Leguizamon, 18-Juan Cruz Mallía, 19-Pablo Matera, 20-Santiago Medrano, 21-Manuel Montero, 22-Julian Montoya, 23-Matias Moroni, 24-Ramiro Moyano, 25-Matias Orlando, 26-Javier Ortega Desio, 27-Guido Petti, 28-Nicolas Sanchez, 29-Nahuel Tetaz Chaparro, 30-Juan Pablo Zeiss.
