A "clerical error" by the International Cricket Council meant the calculation was wrong and Pakistan retain the number one ranking.
Australian cricket chiefs have clarified that Pakistan still top the Twenty20 world rankings, despite Australia's victory in the T20 tri-series also featuring New Zealand and England.
Cricket Australia said this week that Australia would take the number one spot if they were unbeaten in the tri-series, a feat they achieved with a 19-run win over New Zealand in Auckland on Wednesday. But in a statement late Thursday, it said a "clerical error" by the International Cricket Council meant the calculation was wrong and Pakistan retain the number one ranking.
When rating points were rounded off, it said, Australia were second on 125.65, 0.19 points behind Pakistan on 125.84.
It means Australia have still not been rated the number one T20 side in the world since the shortest form of the game began in 2011.
Australia are currently ranked third in Tests and fifth in one-dayers.
Regardless, the Aussies' performance in the tournament took them to their equal-longest winning run in T20 history with six and also lifted them from a lowly seventh in the rankings.
According to the same rankings, Australia sit six points ahead of India on 126.65 but will only overtake Pakistan into top spot if the leaders lose one of their two matches to Scotland in June.
Much of the build-up to Australia's T20 tri-series final centered around the potential for the team to claim the top spot in the rankings for the first time if they were to defeat New Zealand at Eden Park in Auckland.
However, after their rain-affected 15-run win over the Kiwis on Wednesday night, it was revealed Pakistan had retained top spot by 0.19 rankings points.
Here are the ICC T20I Rankings in full:
1) Pakistan - 126
2) Australia - 126
3) India - 122
4) New Zealand - 116
5) West Indies - 115
6) England - 114
7) South Africa - 110
8) Sri Lanka - 91
9) Afghanistan - 88
10) Bangladesh - 72
