Brisbane, Nov 30: New Australian Coach Mickey Arthur said that the national sides rebuilding process may take years as to realise its true standing in world cricket.
The South African is Australia's first foreign coach as he takes charge of Australia on Thursday for the two-Tests against New Zealand.
Arthur said it could take until his contract expires at the end of the 2015 World Cup for Australia to get a true indication of their world standing.
"We have to be realistic," Arthur told reporters. "But if we keep chipping away, in a year or two we could be top of the tree again.
"I guess it (deadline) is the length of my contract, which is until the end of the World Cup.
"That will be after back-to-back Ashes series, a Twenty20 World Cup and a 50-over World Cup.Then you will know exactly where we are at.
"Have some patience with the team but also embrace the excitement of the young talent."
With Mitchell Johnson, Ryan Harris, youngster Pat Cummins and all-rounder Shane Watson Injured, three players are expected to make their Test debuts against New Zealand.
Opening batsman David Warner is expected to debut while young pacers Mitchell Starc, Ben Cutting and James Pattinson are in line for a start.
Arthur hoped the rebuilding process could groom up to 25 players capable of playing international cricket by the end of the southern summer.
"We want to build a sustainable squad. With the amount of cricket we play, it is impossible to have 15 players," he said.
"If by the end of the summer we can bolster our squad from 15 guys capable of playing international cricket at any given time to a squad of 20 to 25, then Australian cricket is going to be in a really healthy state.
"It's by default that this opportunity has arisen (due to injuries) but the benefit is that we are going to have three more guys knowing the intensity required to be in Test match cricket."
Skipper Michael Clarke, who is also included in the selection panel, faved all three fast bowlers in the nets.
"It felt very fast," veteran batsman Mike Hussey said.
"But they were all probably 140kph (90 mph) and there is a bit of movement on those tracks, it was a proper workout. It certainly got the adrenalin rushing."
