In-form halfback Ryan Lonergan reckons Les Kiss has lifted the ceiling on the Wallabies' attack but that they're still far from reaching it ahead of a clash with world champions South Africa.
Kiss remains unbeaten in four Tests as coach, notching wins against world No.12 Japan and then away to No.8-ranked Argentina before a draw against Los Pumas in Mendoza on Sunday (AEST).

They also beat world No.11 Italy in Joe Schmidt's last Test as coach and the unbeaten run has put them ahead of Argentina into seventh before the September 26 date with the Springboks in Perth and next year's home Rugby World Cup.
They left Argentina with a trophy after their first tour win in the country, but were unable to shake the frustration after missing opportunities to ice the contest against an outfit that had two men sin-binned for most of the final 10 minutes.
"We know we've got to be better than what we were, but we can see the growth," said Lonergan, who finished the game acting as flyhalf because replacement Carter Gordon was off with a leg injury.
"If we get our game together on both sides of the ball ... tidy up our attack we've got a chance of pushing them (the Springboks) a long way.
"Joe gave us a great platform to play off and now, with the continuity in the team and little changes and tweaks Les has brought into our attack, the ceiling for our attack has lifted and we look like we have more points in us.
"Now it's about converting it."
Missing a host of overseas-based stars, Los Pumas exposed Australia aerially and the visitors struggled to exit their danger-zone with any authority in what Kiss described as an enlightening fact-finding mission.
The form of fullback Tom Wright, who played his 50th Test in Mendoza, is also under the spotlight after back-to-back kicking errors invited pressure that led to two Argentina tries and a Wallabies yellow card after they had led 14-0.
An unnecessary forearm into a defender after the half-time whistle, when the play was essentially dead, also put his team under the pump, and the side's final attacking opportunity ended with a Wright knock-on.
Joseph-Aukuso Suaalii threatened early but failed to have a huge impact in his return to the No.13 jersey.
The Wallabies' pack has been firing, but with scan results on Gordon's leg still to be returned it leaves plenty of questions around the backline before the Springboks Test and next month's Bledisloe Cup.
"Some of the decisions we've made over this four, five weeks, we got a lot of information from it," Kiss said when asked how he'd approach selections for the next phase of matches.
"It'll narrow the mindset about how we go forward.
"It was important this group knew we'd back them, challenge them in many different ways and we'll get a lot of pay for that down the road.
"We're playing the No.1 nation in the world. What are we, seven or six? So we need to get some things better.
"But the boys will be up for the fight."
