A SUMMARY above and beyond WORKING TOGETHER TO MANAGE AIRCRAFT NOISE Brisbane Airport Corporation (BAC) is committed to ensuring that Brisbane Airport continues to meet the needs of passengers, airlines, industry and the wider Queensland community. The responsibility for managing the airport and aviation operations lies with a number of government departments and agencies working alongside BAC and airlines. A joint responsibility is the management of noise and the impacts of aviation on the community. To highlight the issues and management strategies around noise management, as well as initiatives and efforts undertaken locally and globally to reduce the effects of aircraft noise, BAC and its partners have created the booklet “Above and Beyond”. This document provides a summary of the booklet, which is available in its entirety at www.bne.com.au.
