Travis Head made the fastest one-day international century by and Australian against Pakistan as the "happy" tourists eased to a 88-run victory in the series opener in Lahore.
Head reached three figures off just 70 balls, before falling for 101. He shared in an opening stand of 110 in 14.4 overs with Aaron Finch (23) before Ben McDermott chipped in with 55 out of Australia's total of 313 for seven.
Head then took two wickets and a catch as Pakistan were dismissed for just 225 in their reply, despite a 103 from Imam-ul-Haq and 57 from captain Babar Azam who had helped the hosts to 120 for one in 24 overs.
Wickets fell regularly after that with leg-spinner Adam Zampa starring with four wickets.
Zampa: We're happy
After helping his side to victory, Zampa said he and his team-mates were relishing their first tour of Pakistan, the hosts having led a nomadic existence for most of the last 20 years due to security concerns in their homeland.
"It's been great," he said. "It took us 24 years since the last time we were here, but we feel safe, we're happy, the crowds are amazing."
Zampa and his team-mates have been working with Daniel Vettori in recent days, the former New Zealand spinner having been appointed in a consultancy role for the limited-overs leg of the tour.
But his advice has all been about keeping things simple, according to Zampa.
He added: "It's all just tactical stuff. We do a bit of research on the opposition and then hash over the plans before we go out so try to keep it pretty simple."
Man of the match Head was delighted to take his chance as an opener.
Openers 'set platform'
He said: "It's nice to get a look at the top, get an opportunity and take it. I felt like we set the platform really well, Finchy and I, so we knew that with the dew coming in it may be tough to bowl later in the innings."
Pakistan will look to bounce back in Thursday's second game of the three-match series.
Their skipper, Babar Azam, admitted Australia's flying start with the bat proved costly.
"We let them score too many runs in the first 10 overs," he assessed. "We started poorly and then gave away too many runs at the death. While Imam and I were batting, we felt we had the chase under control but then lost wickets in clumps and couldn't recover."
