Australia have played eight Twenty20 Internationals since the last World T20 in Bangladesh two years ago, including a run of just one game between November 2014 and January this year. The side was also whitewashed 0-3 by visitors India on Sunday in the three-match series.
Ryan Harris, who retired before the Ashes last year, believes the scarcity of matches makes it difficult to build a meaningful campaign for World T20.
"Personally, I think it's a waste of time having a World T20. Last year we played one T20, this year I think we play six. To take it seriously, you need to play a lot more than that when there's a World Cup involved," Harris said.
The reigning World Champions in the 50-over format, after playing the T20I against India on Sunday, will play their first One-Day International (ODI) against hosts New Zealand on Wednesday. Harris said the tight international schedule - with three days gap between two games - has hindered the team's preparation for the T20 showpiece.
"Scheduling there doesn't exactly let you have your best team out on the park. You've got your one-day team, who's probably half of your T20 side, having to get over to New Zealand and acclimatise. I know when we get our best side on the park - that wasn't far away from it yesterday - I know we'll perform well," the 36-year-old said.
