Australia's batsmen exorcised their Ashes demons on the seam-friendly wickets of New Zealand to reclaim the No.1 Test ranking but face another Achilles heel if they are to stay there - spin on the subcontinent. 
Captain Steve Smith has challenged his batsmen to overcome the poor record on the dusty tracks of Asia after they completed a 2-0 series win over the Black Caps in Christchurch.
The Australians have their eyes set on creating a dynasty but understand they cannot achieve that goal if they do not improve their record away from home.
The victorious campaign in New Zealand, Smith's first Test tour as captain, is a step in the right direction for a team that has not won a series on the subcontinent in 4\xC2&#189; years. While Australia's opposition has been only moderate this summer, they have undergone huge transition in their batting and bowling ranks after the Ashes loss.
Their deep well of pace talent ensured they claimed 20 wickets in six of eight Tests despite being ravaged by injuries and retirement, while their batting, considered to be an area of vulnerability, has become a strength. Their batsmen have scored 19 centuries across eight Tests with all-rounder Mitchell Marsh the only member of the top six not to reach three figures.
Their ability to make big hundreds was the major difference between Australia and New Zealand across the two series.
"I was confident with the guys who were coming in that they'd do the job," Smith said. "I think we scored 15 hundreds as a whole in our summer at home and big hundreds are what put your team in a very good position and I've been really pleased with the way the guys have been able to get through tough periods and be willing to bat for long periods of time."
Australia's next series is in Sri Lanka in   July-  August. They won 1-0 in their last visit, in 2011, but have since lost all six Tests in Asia - and by considerable margins. "We want to win every series that we play and winning away from home is a big goal of mine and the team," Smith said.
Australia comfortably ran down New Zealand's target of 201 with seven wickets in hand at Hagley Oval. Joe Burns top-scored with 65, while Smith made an unbeaten 53 off 46 balls.
