The "Say Yes" campaign was started with actors Cate Blanchett and Michael Caton appearing in a national television advertisement.[2]
The demonstrations were organised by Say Yes Australia, a coalition of community groups, environmental organisations, unions, associations and other groups and was apolitical. All demonstrations were peaceful with no injuries or arrests.
The Federal Treasurer, Wayne Swan, attended the Brisbane rally.[2] In Canberra, the ACT Chief Minister, Katy Gallagher, was in attendance.[3]
