Australia coach Darren Lehmann is not giving too much away when it comes to Australia’s choice of spinners for the upcoming Test tour of Bangladesh.

Australia have an off day on Thursday and the cricketers will get some much needed rest before leaving for Dhaka on Friday.

While Australia's spin combination is source of intrigue, Lehmann revealed very little on his options - Adam Zampa, Ashton Agar and Mitchell Swepson. Nathan Lyon is a definite choice for chief spinner in the lineup.

Aussie spinners Ashton Agar and Jon Holland had dominated proceedings in the final day of Australia’s intra-squad match at Darwin in conditions which mimic Bangladesh’s.

Holland was obviously not part of the Bangladesh Tour setup but Agar has seen his chances of partnering Nathan Lyon improve in the Tests after his four wicket haul in the Darwin practice match.

He bowled beautifully today," Lehmann said of Agar.

"Obviously he's on tour, so you'd have to look at that, and obviously Swepson's there.

"I thought [Jon] Holland bowled really well today as well, so we're starting to get some depth in our spinning department which is important."

Swepson failed to impress and struggled with figures of 0-94 and 0-34. Adam Zampa is also part of the spin mix and he took two late wickets to end the match at Darwin.
