Factors threatening the waters of southeastern Australia except

1. Pollution: Industrial runoff, agricultural runoff, and sewage discharge can all contribute to pollution in the waters of southeastern Australia. This can harm aquatic ecosystems and pose risks to human health.

2. Climate change: Rising sea levels, increased ocean temperatures, and changing weather patterns can all have negative effects on the waters of southeastern Australia. This can impact marine life, coral reefs, and coastal communities.

3. Overfishing: Unsustainable fishing practices can deplete fish stocks and disrupt marine ecosystems in southeastern Australia. This can have cascading effects on the entire food web.

4. Invasive species: Introducing non-native species into the waters of southeastern Australia can disrupt the ecosystem and outcompete native species for resources. This can lead to imbalances and negatively impact biodiversity.

5. Habitat destruction: Coastal development, dredging, and other human activities can lead to the destruction of important habitats such as seagrass beds, mangroves, and wetlands. This can have far-reaching consequences for the health of the waters in the region.
