Cameron Bancroft and Peter Siddle have been the stand-out Australian performers as England's first-class competition resumed this week, with the Ashes looming on players' minds.
Victoria seamer James Pattinson was a notable absentee from the Nottinghamshire side that is facing Essex at Chelmsford in a Division One clash, with the quick taking a cautious approach to his return after picking up a "slight" side strain.
Pattinson missed Nottingham's one-day semi-final defeat last weekend and had not recovered in time to take his place in the County Championship clash that started Tuesday.
But fellow Victorian Siddle turned out for Essex and has now passed 100 County Championship wickets, including 46 in his ninth game for Essex and now boasts a career total of 551 first-class victims, including his 214 in Baggy Green.
Siddle claimed 2-31 from 17.3 overs with eight maidens in Nottingham's first innings that saw them bowled out for 187, and backed it up with 1-15 from nine overs (two maidens) so far in the second innings as Notts collapsed to 6-89.

Siddle was also key with the bat, hitting an unbeaten 40 from 78 balls to help rescue his side from 8-158 with an 81-run stand with Simon Harmer (43) that helped Essex to 241.
At New Road, Bancroft hit 70 for Durham after winning the toss and opting to bat in his side's Division Two clash with Worcestershire.
His knock was important as the Durham top order collapsed around him. Bancroft, at No.3, walked to the crease in the second over and his side quickly fell to 3-14.
But a 149-run stand Jack Burnham (76) helped steady the ship as Durham went on to be bowled out for 273 and are currently 48 runs behind Worcs who reached 6-321 after two days.
The news was not as good for the other Australians in county action with a trio of Queenslanders all failing to make a major impression.
Matthew Renshaw was dismissed for 16 in his only innings so far in Kent's Division One match against Yorkshire in Canterbury.
Having bowled Yorkshire out for 210, Kent were dismissed for 296, while Yorkshire have built an 80-run lead to be 3-166 after two days with former England Test batter Gary Ballance unbeaten on 57 at stumps.
At Old Trafford, Joe Burns was dismissed for 10 in his first knock for Lancashire, having resumed his innings on six on the second morning batting at No.3.
It will no doubt be a frustration to Burns he fell in the early going with Lancashire putting on a 152-run partnership following his wicket, led by 97 to England's Ashes opening hopeful Keaton Jennings.
And in Wales, Marnus Labuschagne was dismissed for a second-ball duck batting at No.3 for Glamorgan as the home side reached 8-241 at stumps on day two.
They still trail Gloucestershire by 222 runs after the visitors piled up 463, with 14 overs of Labuschagne's leg-spin going for 51 runs without taking a wicket.
