Robinson is challenging the players who defeated Fiji 23-10 last weekend to improve their performance for the meeting with the world’s third ranked side.
He said: “We are giving the players the opportunity to perform against the Wallabies, who are a top quality international side – the sort that everyone wants to test themselves against.
“Competition for places is intense and we’ll be watching the Scotland A game against Tonga in Gala on Friday night very closely.
“But we are saying to the players for Saturday step up this weekend and show improvement.”
