The title is India's first since 2012, having been beaten in the final by West Indies two years ago, and the head coach hopes this success is the first of many for this crop of players.
India were placed in Group B, along with Australia, Zimbabwe and Papua New Guinea.
Since thrashing the Aussies by 100 runs in their opening match, India have proved simply unstoppable, winning five successive games easily.
Days later, they returned for their second group game against unfamiliar opponents - Papua New Guinea. All-rounder Abhishek Sharma, along with fellow left-arm spinner Anukul Roy, would look to exploit the Australian batsmen's weaknesses against spin. "I think India have to be favourites, especially (as) they beat us here", said Harris.
Shaw's counterpart Jason Sangha was keen to brush Australia's defeat to India in the pool match under the carpet and wanted to focus on the future rather than dwelling on the past.
India opened with a requirement to chase the target at an overrate of 4.34 runs.

The oranges appear to have come from the town of Carmona, where a theft had been reported at a warehouse some hours earlier. When police tried to pull the cars over, the vehicles took off leading to officers chasing them through a dirt road.
Australia had previously beaten Afghanistan in the sem-final. In a disciplined bowling display, Indian bowlers bowled out the "young Tigers" for 134.
India made an imposing 328/7 from their 50 overs before their bowlers dismissed the Australians for 228 to secure a 100-run win. At the crease, after Shaw's departure, are Kalra and Shubman Gill.
Expensive Porel: Ishan Porel has not found rhythm in his first 2 overs and has been punished for runs. The batting efforts have been led by the skipper Prithvi Shaw who has scored a plethora of runs all through the tourney. For India, Ishan Porel, Anukul Roy, Shiva Singh and Kamlesh Nagarkoti took two wickets each. "The middle order also controlled the innings well". "As a captain, I'm focussing on my own team, what we can do in the match tomorrow, what all we've to do in different situations" - Prithvi Shaw, India captain. India's fielding has also been exemplary in the tournament so far.
"They've got some really good bowlers there that bowl good pace and have handsome actions". It's a challenge for our guys.
After their loss against India, Australia cruised past Zimbabwe and PNG, but had to sweat it out against England in the quarter-final, successfully defending 127, thanks to Lloyd Pope's 8-wicket haul.
