Australians were very good at reading the pitch. They have played a lot of cricket in India. They knew that the pitch was made up of black soil, which gave a good turn and bounce in the afternoon and became absolute rode under light and dew. This is the reason they have decided to bowl first in the final match.
I don't know why India chose this particular pitch for the final match and did not select the pitch which would help them in batting. Their batting was exceptional, and they should have made a batting pitch on the final day.
TRP generates revenue, and the money is what everyone is after. So, you can not blame BCCI for organising a day/ night match. Usually, the ICC tournament matches are Day/ Night because of the spectators' turnout.
Australians are an intelligent nation, they look deeply into batting, bowling, fielding and the effects of pitch and weather. They never see whether it is Asian wickets or Western wickets, they always take decisions according to the occasion. Like us, they do not depend only on batting and bowling, but take full advantage of the ground environment. This is the reason why he became the champion for the sixth time, which they certainly deserves.
I think India won the matches on the batting pitch in all the matches of the World Cup and finally faced the bowling pitch, because in all the Indian matches before the final, the Indian batsmen showed great batting, and kept the opposition bowlers under pressure, but in the final match, their batsmen and bowlers faced a lot of pressure.
