Scotland captain Scott Murray says defeat of Samoa has given his side renewed hope of an historic victory over Australia next weekend. "Of course it will be difficult against the Wallabies, we are not unrealistic," he said.
"But I think we have got the team that can do it if we play our systems.
"If we can show the kind of commitment we showed against Samoa and a bit more, there is every chance we can beat Australia next Sunday."
Friday's 38-3 victory over Samoa in Melbourne ended a run of five Tests without a victory for new Scotland coach Matt Williams.
Five tries in the final 43 minutes gave the Scots their first victory in the southern hemisphere, outside of a World Cup, since 1982, against Australia.
"Some of the defence was absolutely brilliant, throwing themselves at rucks, putting everything into it," said Murray. "I was very proud of the boys. Some of these Samoan guys are huge and our boys launched themselves. And it was controlled.
"It is good to get a win under the belt. We hope this win will signal better things to come, give a bit of confidence to the guys."
Scotland have retained belief in the systems being implemented by Williams, despite being consigned to the Six Nations wooden spoon.
Stand-off Gordon Ross said: "I think it is just rewards for the hard work the guys have put in.
"There just seemed to be a lack of confidence during the Six Nations.
"I think it is a gradual progression. We are improving on small parts of the game and we just have to piece it all together better now.
"The way we trained this week, we approached the Samoa game in the right attitude and, when we got that first try, it gave us a great belief we could win the game."
The Leeds stand-off was overlooked for the Six Nations campaign but scored the opening try against Samoa after being chosen ahead of Dan Parks.
"I thought, when Dan Parks started the game against Ireland, he did pretty well, he got the team moving forward a lot better than they had in the past," said Ross.
"The coaching staff told me just to carry on playing the way I was and I would get an opportunity.
"With my try, the hard work had been done by the forwards. They battered the gain line, sucked them in and from that distance it was quite easy."
Samoa captain Semo Sititi concluded: "I think having to defend so much early on cost us the match because we felt tired and that told in the second half."
