Galle

The 28-year-old was Australia's leading wicket-taker in their 2-0 Test series win in Sri Lanka but was reported following the second Test in Galle.

"The Australian team was notified of the match officials' referral following the second Test against Sri Lanka in Galle and will support Matt through the process of clearing this matter," Cricket Australia said in a statement released today.

"Fortunately hit that one in the gap so nice to get that one away," Smith, who was 64 not out at tea in Galle, told Australia's 7Cricket.

His figures eclipsed the 6-50 he took against Sri Lanka at Galle in August 2016 and underlined his mastery with the pink ball - nobody comes close to his 72 wickets in day-night Tests.

Kamindu Mendis continued his remarkable start to Test cricket by scoring his fourth century on day one of the first Test against New Zealand in Galle.
