England beat Australia by 6 wickets. Australian team did put up a good performance but that was simply not enough to beat England. They had a target of 300+ in mind and they did cross it, but English team is in good tempo these days and they achieved the target very easily.
Australia scored 310 in their 50 overs, which is a very good score against most teams and in most grounds. But this is a team which scored 481 in the previous match. A score of 300+ is not going to intimidate them. England had a very good start as well, with Jason Roy scoring a century as well. In the end, they chased it down with ease.
