Cummins into bat for Australia's top order

Opener Marcus Harris won't play the first Test against Pakistan at the Gabba due to poor form

Pat Cummins has warned big-talking Pakistan to underestimate Australia's batting line-up at their peril this summer.

With the tourists' exciting new pace attack dominating Australia A in Perth this week, there's been a lot of bluster coming from the Pakistan ranks as they chase an historic first-ever Test series win down under.

Star opener David Warner was particularly poor, averaging just 9.5 in 10 innings, during Australia's Ashes series in England, while Marcus Harris and Usman Khawaja have both been dropped for next week's series opener in Brisbane.

Cummins, though, said bring it on if Pakistan considered Australia's top order to be brittle, or even a weak link.

"Yeah perfect. Obviously the pink-ball Aussie A game over in Perth, you can't look into that too much," Cummins said on Friday.

"The pink ball is really hard to bat (against) at times. The ball zips around.

"We're really confident when we play at the Gabba. Our record there starting off the summer is really good and we have got guys who have been churning out runs.

"You've got Steve Smith; the best batter in the world, Dave Warner, Marnus (Labuschagne), Trav Head, Matt Wade. These guys have all scored big runs in Shield games or Test matches the last couple of months.

"I wouldn't be looking too much into the last week."

Cummins did concede Australia's batsmen could have their hands full at times dealing with the likes of young left-arm quick Shaheen Afridi, 16-year-old sensation Naseem Shah and veteran seamer Imran Khan.

"It seems like they've got a couple of really young bowlers who are bowling quick and quite lively, which always seems to be a trend with Pakistan," he said.

"Ever since Wasim Akram, Waqar Younis and Shoaib Akhtar, they always seem to have young, quick bowlers.

"It's going to be a challenge for us.

"But these conditions over here, they can be fast and bouncy but they can also be some of the toughest to bowl on."

Regardless of whether he gets the new ball or not, Cummins personally can't wait to get stuck into Pakistan for the first time at Test level.

"If it happens, it happens. It doesn't bother me too much to be honest," the in-form quick said of his preference to open the attack.

"The good thing is all the Test matches where I've come on and bowled first change, it's only because we've had gun opening bowlers.

"So we're lucky we're blessed with that.

"I'm just really looking forward to not only Pakistan but also New Zealand, who I've never played either in a Test match.

"So there's quite a few unknowns going into both those series."
