Sydney: Australia vice captain David Warner has accused New Zealand fans of going “too far” in their abuse of the tourists during the two-test series which concluded on Wednesday.

Both captains paid tribute to the spirit in which the series, which Australia won 2-0, had been played but Warner suggested that goodwill had not extended to the stands at Wellington’s Basin Reserve and Hagley Oval in Christchurch.

“Some of the stuff was pretty derogatory and vulgar,” Warner told reporters at Sydney Airport on Thursday.

“You get your odd banter here or there, but when they’re talking about people’s families it takes it a little bit too far.

“We don’t expect to wake up and be hounded for six or seven hours,” he added.

“The upsetting thing was I know if my two daughters were in the crowd, I wouldn’t want them listening to that kind of stuff.” While New Zealand have prided themselves on playing the game in the right spirit over the last couple of years, Australia have maintained a reputation for on-field aggression.

Australia captain Steve Smith was fined 30 per cent of his match fee after an angry exchange with umpire Ranmore Martinesz on day four of the second test.

Warner, once the self-confessed “attack dog” of Australia’s sledging effort, said Australia would continue to play the game their way.

“We have a passionate brand,” Warner added. “If you look back at the history of Australian cricket we have an aggressive style.

“We’ve got keep playing our brand of cricket and not stepping over that line.”

Meanwhile, Australia coach Darren Lehmann has praised his team’s refurbished batting order for taking the pressure off a depleted bowling attack by scoring big totals in the test series sweep over New Zealand.

New opener Joe Burns was named man-of-the-match for setting up the Christchurch win with scores of 170 and 65, while the re-instated Usman Khawaja capped his golden summer at number three with a knock of 140 in Wellington, his fourth test century in five matches.

“We’ve lost a big chunk of our side in one hit. But they changed around pretty quickly, we took a punt on a couple of players and they did well,” Lehmann told reporters.

“We’ve probably got the better of the conditions batting-wise, but that’s the way it goes in this game sometimes.

“I’m pleased we’ve made big runs in the first innings. That helps, it certainly gives you more time in the game.” Australia’s pace bowling stocks, weakened by the loss of spearhead Mitchell Starc to injury before the series, were further tested with injuries to James Pattinson and his first-test replacement Peter Siddle.

And senior paceman Siddle faces a lengthy period out of the game with a stress fracture in his back, Cricket Australia said Thursday.

“Peter returned to Melbourne on Monday and had scans following the bout of back pain he suffered during the first Test in Wellington,” team physiotherapist David Beakley said in a statement.

“Unfortunately those scans have indicated a stress fracture in his lower back.

“He will now require a significant amount of time away from the game with a lengthy rehabilitation process.”

Beakley said the time off cricket will enable Siddle to also have exploratory surgery on his left ankle.

“Once that surgery is complete we will have a better idea of his prognosis and likely rehabilitation time frame,” he said.

Siddle has taken 208 wickets in 61 Tests at 29.88.
