Fiji rugby coach John McKee says his side need to be more clinical with the ball in hand and take the opportunities on offer.
The Wallabies defeated the Pacific Nations Cup holders 37-14 in Melbourne, with Suva-born Henry Speight and Israel Folau both scoring twice for the home side.
The Flying Fijians were kept scoreless until Vereniki Goneva found the tryline in the 62nd minute before Timoci Nagusa added another consolation four minutes from full-time.
John McKee said it was a frustrating start to the international window.
"We did a lot of quite good things in the game but on the scoreline for us it was disappointing," he said.
"We've got things to work on but I think we can take a lot of positives from that game for the rest of our series going forward.
"We had enough ball in that game to do very well but we didn't execute as well as we needed to - certainly our conversion rate of possession to points was poor in comparison to the Wallabies."
The Flying Fijians have a chance to rectify their mistakes on home soil against Italy this Saturday.
The teams last test was also in Suva, three years ago, where the home side defeated the Azzurri 25-14.
John McKee believed the gap between tier one and tier two nations was closing and said Italy presented a completely different challenge to Australia.
"We need to play those games to get better," he said.
"We're sort of the top ranked tier two team but we do know that there is a big step up in the performance required to be successful against the tier one nations."
John McKee said some more players have joined them in camp this week after playing in the French Top 14 playoffs and he will continue to rotate his squad in the build up to next month's Rugby World Cup qualifiers against Tonga and Samoa.
