Social aspects

Approximately 1 million people live within the catchment area with a highly diverse population including Chinese, Greek, Arabic, Italian, Spanish, Indian, Vietnamese, Korean and Macedonian communities as well as many others from culturally and linguistically diverse backgrounds.

During the last two centuries much of the natural vegetation and original creeklines have been removed or significantly modified. Despite these impacts, the bushland and waterways that remain are now receiving a helping hand as a significant number of highly committed individuals and groups are slowing restoring these important areas. In 2007 over 2,500 people across the catchment volunteered their time to look after their local environment, contributing over $500,000 worth of on-ground works in one year alone.
