Today we have 4th ODI match b/w AUS vs ENG. i don't think Australia will come back in this match. England already won this series and leading by 3-0 if it goes 5-0 also no surprise.
Suppose if England play first batting today also we can expect a big score.
Australian batting 1st and after 34 overs they have scored 178 for 1. Even if they score 310 to 320, I think England can chase down the total, we witnessed what happened in the 3rd odi, England are very confident side now and they have explosive batsmen like Jason roy, hales, Morgan, Jos Butler. Australian will have to bowl well in order to restrict England.
