The Tigers remain ninth in the standings but have increased their rating to 87 points, moving closer to eighth-placed England, who sit on 89 points.
Before the three-match series, Bangladesh had beaten Australia only once in ODI cricket, back in 2005.
However, victories in the opening two matches secured their maiden ODI series win over the world champions, creating a new chapter in the team's history. Although Australia avoided a whitewash with a one-wicket win in the final ODI, Bangladesh still emerged as series winners.
In the third match, Shoriful Islam's six-wicket haul nearly inspired Bangladesh to another victory before Australia edged home in a tense chase. The success in the first two games, however, had a positive impact on Bangladesh's ranking points.
With a rating of 87, Bangladesh are now just two points behind England. They also hold a comfortable advantage over 10th-placed West Indies, who have a rating of 73.
The improved ranking is significant in the race for direct qualification to the 2027 ODI World Cup. Hosts South Africa and Zimbabwe have already secured automatic qualification, while the next eight highest-ranked teams will also qualify directly. Teams inside the top nine of the ICC ODI rankings on March 31, 2027, will avoid the qualification tournament.
The series also affected Australia's ranking as consecutive defeats in the first two ODIs dropped them to fourth place, but their victory in the final match lifted them back to third, with only a fractional difference separating them from fourth-placed South Africa.
