Australia dominated India in batting, bowling and fielding in the Adelaide match to bolster their status as favourites to win the global showpiece which starts on Saturday.
India have been in wretched form Down Under, however, going winless from their three matches in the tri-series against England and Australia in recent weeks.
“It’s just a matter of time until their batting order clicks,” Hazlewood told reporters in Melbourne on Tuesday.
“They’ve got some outstanding players and they’ve all got great records. I think it’s just a matter of time before they get going.”They’re a very dangerous side.”
Australia have been in ominous form in the lead-up, going undefeated to win the tri-series despite missing injured captain Clarke, who is nonetheless expected to play in the team’s warm-up match on Wednesday against United Arab Emirates at the Melbourne Cricket Ground.
James Faulkner’s side strain has been the only major fly in the ointment and Hazlewood underscored the fast bowling all-rounder’s value as “an edge” over the 13 other teams who will compete at the World Cup.
