Beaches and sand dunes

This component has changed from 2011.

  • This component has been moved from Marine environment to Coasts

Most beaches are in good condition but are threatened by debris, mechanical cleaning and compaction by 4-Wheel Drives. Sand dunes are heavily impacted by foreshore development, invasive species and historical practices of 'stabilisation'.

Lagoons

This component has changed from 2011.

  • 'Gulfs, bays, estuaries, lagoons' has been moved from Marine environment to Coasts
  • 'Gulfs, bays, estuaries, lagoons' has been split into 'Lagoons', 'Estuaries' and 'Bays'

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.

Recent trends are unclear, but their condition is affected by coastal development, organic enrichment, recreational fishing and entrance modification.

Estuaries

This assessment summary component has changed from 2011.

  • 'Gulf, bays, estuaries and lagoons' has been moved from Marine environment to Coasts
  • 'Gulf, bays, estuaries and lagoons' has been split into 'Lagoons', 'Estuaries' and 'Bays'

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.

Approximately half are significantly impacted by historical and contemporary developments. Affected by pollution, hydrological modifications, the addition of artificial structures, dredging, shipping, invasive species and recreational and commercial fishing.

Bays

This assessment summary component has changed from 2011.

  • 'Gulf, bays, estuaries and lagoons' has been moved from Marine environment to Coasts
  • 'Gulf, bays, estuaries and lagoons' has been split into 'Lagoons', 'Estuaries' and 'Bays'

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.

Heavily used bays suffer from contamination issues, introduced species, increased physical disturbance, fishing and the addition of artificial structures.
