''We know that this is a highly competitive bidding process.
However, united by a common goal, we hope the ICC will award the 2011 ICC World Cup to Australia and New Zealand,'' the Cricket Australia chief said in a statement.
''Australia and New Zealand have a proven track-record for the presentation and seamless delivery of world-class sporting events,'' Mr Sutherland said.
Both countries have already hosted the tournament jointly once in 1992, when finals were held at the Melbourne Cricket Ground.
The countries are yet to decide the venue of the final in 2011 but have agreed to split the matches equally.
New Zealand Cricket Board CEO Martin Snedden said infrastructure for the mega event was already in place and both the countries are fully equipped to host the event.
''We are confident that we have a world class bid. Both countries have the capability to host an outstanding event,'' Snedden said.
''We have fantastic venues, solid infrastructure and professional staff who are experienced in event management at the highest level,'' he added.
Meanwhile, Asia's joint bid, consisting, India, Pakistan, Bangladesh and Sri Lanka, is still being worked out even as the deadline to submit the bid ends today.
The host of the 2011 edition will be announced in July at the ICC's annual conference.
