The Commission Against Corruption (CCAC) of Macao plays a vital role in ensuring fair and transparent elections. It combats electoral bribery by monitoring campaign activities. Citizens can report suspected violations via hotline, online platform, or in-person visits to the CCAC. The CCAC also conducts on-site inspections and intervenes early when irregularities arise.

In preparation for the 2025 Legislative Assembly Elections, the CCAC launched a comprehensive campaign to promote clean elections in Macao, China. As part of its outreach efforts, the CCAC organised a series of community promotion tours, which attracted thousands of participants. To further engage the public, the CCAC expanded its presence across social media platforms, released tailored animated content and launched a radio series to address public concerns.

The CCAC organised a sticker design contest to promote clean elections, which received several hundred entries from participants in both the youth and open categories. The contest culminated in an award ceremony celebrating the winning designs. Additionally, a WeChat game was launched, offering participants the chance to win prizes by answering questions related to election law and clean election scenarios.

The CCAC also participated in the Legislative Assembly Elections Campaign Kick-off Day on 30^th August, where it promoted the values of clean elections among candidates, campaign teams and voters.

The Legislative Assembly Elections were successfully held on 14^th September 2025, thanks to the joint efforts of the CCAC and the citizens of Macao, China.
