Will Aussie bowling attack be easier to make runs than English attack??

[yaseer]

Somerset has just beaten Australia in a practice match at Taunton.
Somerset chased 342 in 46.5 overs. here is the link to the cricinfo scorecard:

Now the question is..............
Is the aussie bowling line up is becoming aged and do Bangladesh have better chance to score runs against Australia than England?

Mcgrath, Gilespie, Kasproitch.......all are now a days bowling around 82 miles per hour........may be if we bat well........it is possible to make runs against Australia.
