After the third round of counting,

India's vote point = India's vote point after the second round + Number of votes with England as "First Rank” and India as "Second Rank” + Number of votes with England as "First”, West Indies as "Second” and India as "Third Rank”. + Number of votes with West Indies as "First”, England as "Second” and India as "Third Rank”.

= 118 + 18 + 22 + 16 = 174 votes.

Therefore, Australia's vote - count = 350 - 174 = 176 votes

Therefore, Australia won by a margin of 176 - 174 =2 votes.
