While the world swoons over the mouth watering 5 match England versus India test series, Bangladesh has quietly been putting in a performance that will go down in cricket history.

With 5 Twenty20s on the horizon, Australia embarked on a tour of Bangladesh that should have been the perfect preparation for Australia's bid to win the upcoming ICC T20 World Cup.

On the contrary, however, this tour did the opposite. 

Bangladesh, while still clear underdogs, has raised eyebrows on the international stage with their 4-1 drubbing of Australia, something the ozzies were surely not bargaining for this close to a major tournament.

In the fifth and final Twenty20, Australia were bowled out for 62 in Mirpur, and ended up losing by 60 runs.

That is their lowest Twenty20 score in history. Yes, in history!

To make matters worse for the tourists, they were all out in 13.4 overs, their shortest innings in 144 years, with only stand-in captain Matthew Wade and Ben McDermott passing four runs.

How remarkable is this performance? For context, the Tigers had never beaten Australia in a T20 before this five-game series.

It is important to note that Australia were not fielding there full strength side for the series, with key players like Steve Smith and Glenn Maxwell missing.

Yet still, with the T20 World Cup in the United Arab Emirates and Oman scheduled to start on 17 October, Australia need to make changes sharpish if they are serious about winning the world cup.

Meanwhile, could we be seeing the start of the greatest world cup performance in living memory? We can't guarantee Bangladesh will win, but if they replicate these performances during the tournament, they'll go a very long way to upsetting the status-quo and having a shot at winning it all.
