Abu Dhabi Grand Prix: Romain Grosjean on top of opening practice

Jul 2: Cricket Australia has decided to not use the Dukes ball from this summer's Sheffield Shield, having used it alongside Kookaburra for four seasons.

CA has confirmed that the Kookaburra ball will be used for the entire 2020-21 first-class season.

Australia has been using Dukes ball since the 2016-17 season in Shield matches with an aim to help its cricketers prepare for the hostile English conditions.

CA's Head of Cricket Operations, Peter Roach, said the decision to axe the Dukes was the right call. "The introduction of the Dukes ball has been a worthwhile exercise, particularly in the lead up to overseas Ashes series where the Dukes is used so well by our English opponents," Roach said.

"We have been happy with how the ball has performed when used in Australian conditions over the past four seasons. We do, however, feel that reverting to one ball for 2020-21 will provide the consistent examination of our players over a full season that CA and the states are presently seeking. The Kookaburra is the ball used for international cricket in Australia and many parts of the world and we see benefits this season of maximising our use of it," he added.

Roach said the ineffectiveness of spinners in first-class cricket in recent times played a role in CA's decision to do away with the Dukes. "We have noted that spin bowlers in the Sheffield Shield have been playing less of a role in recent seasons, most notably in games when the Dukes ball is in use. We need spinners bowling in first-class cricket and we need our batters facing spin. We hope that the change to one ball will have a positive benefit here," he said.

The CA official, however, didn't rule out the possibility of re-introducing it later.

"We see a definite opportunity to reintroduce the Dukes ball at some stage in the future."

Melbourne, Jun 20: If 15 teams can be allowed to enter Australia for the T20 World Cup then fans will not be stopped from watching live action from the stadiums, Cricket Australia's interim CEO Nick Hockley said on Saturday.

Hockley replaced under-fire Kevin Roberts, who recently got the boot from Cricket Australia, which is grappling with financial woes.

Different possibilities are being worked out for the T20 World to go ahead as scheduled later this year and one of them is to host the tournament before empty stands in the wake of COVID-19 pandemic.

However, Hockley said crowds will be allowed, though, hosting 15 teams with players, officials and support staff is "complex" as of now, hinting that probably the ICC flagship event could be pushed back.

"The reality is, and we've got much more understanding about this in recent weeks, is crowds are most likely to come back before international travel. Our biggest challenge is getting 15 teams into the country," Hockley told cricket.com.au when asked if he would like to see the World Cup proceed without fans.

"If I compare it with the prospect of a bilateral tour, you're talking about bringing one team in and then playing individual matches. But the prospect of bringing 15 teams in and having six or seven teams in one city at the same time, it's a much more complex exercise."

When specifically asked whether crowds would be permitted by the time borders have opened to the point that 15 teams will be allowed to travel to Australia, Hockley replied in an affirmative.

"That's the current thinking, yes."

Hockley said it came as a shock when he was asked by Cricket Australia to replace Roberts.

"I've had very mixed emotions. I was very shocked to be asked. I didn't see it coming at all, so I probably haven't had time yet to process it. I feel very sad for Kev (Roberts). On the other hand, I feel this is a massive privilege to be asked, it's a massive responsibility and a massive opportunity even if it's only for the next few months," he said.

Hockey did not commit when asked if he would like to assume the role full time, but he did say that he would quit as CEO of the T20 World Cup Organising Committee.

"My approach throughout my entire career has been to focus on doing the best job I can with what I've been tasked with, and the future will look after itself. And I'll continue the same approach.

"That's (T20 World Cup) been a real priority over the last 48 hours. We're reasonably well progressed and we will be appointing an interim because you just can't do both," he said.
