Tomás Cubelli will start at scrumhalf as one of four changes to the Argentina starting lineup for Saturday's Test against Australia in Perth.

Cubelli, who plays for the Brumbies in Super Rugby, is preferred to Martín Landajo.

Elsewhere in the backline, Santiago González Iglesias and Lucas González Amorosino replace last week's centre pairing Juan Martín Hernández and Matías Orlando in the side, but Matías Moroni shifts from wing to outside centre with Amorosino starting out wide.

With lock Guido Petti out through injury, flank Javier Ortéga Desio moves to No 4, granting Juan Manuel Leguizamón a starting berth in the back row.

Argentina – 15 Joaquín Tuculet, 14 Santiago Cordero, 13 Matías Moroni, 12 Santiago González Iglesias, 11 Lucas González Amorosino, 10 Nicolás Sánchez, 9 Tomás Cubelli, 8 Facundo Isa, 7 Juan Manuel Leguizamón, 6 Pablo Matera, 5 Matías Alemanno, 4 Javier Ortéga Desio, 3 Ramiro Herrera, 2 Agustín Creevy (c), 1 Nahuel Tetaz Chaparro.
