Suliana Siwatibau (née Kaloumaira) is a former Fijian political activist, who served as the Chairperson of the Pacific Centre for Public Integrity (PCPI) as of January 2007.

[8] She said on 16 June 2005 that the widespread opposition to the legislation was motivated not only by its contents, but also because of what she said was the government's unwillingness to proceed with its development in a transparent and consultative process.

Reacting to the decision of the Great Council of Chiefs to endorse the bill, Siwatibau said on 29 July that they had not been given enough time to deliberate on the matter.

Over four fifths of the Great Council members are delegates of the country's fourteen Provincial Councils, which all endorsed the bill – something which came as no surprise to Siwatibau as they had been briefed only by the government and were required to make a decision on the spot, without being given the opportunity to hear alternative viewpoints.

They had three sons – Simione Ramacake, Ropate Rakula, and Atunaisa Taleasiga – and one daughter, Asenaca Tania Tuivanuavou.
