Australian Twenty20 captain Michael Clarke has thrown his support behind the new partnership between Cricket Australia, Foster's Group, Diageo Australia and the Nine Network, by encouraging fans to 'Know When to Declare'. 

In the latest ad Clarke encourages sports fans to enjoy having a drink with friends but in a responsible way by saying: "Know your limits and know when to declare."

The campaign is designed to demonstrate the benefits of making the right decisions on and off the field and reminds young adults that they are ultimately responsible for their own actions.
