Our water quality monitoring program has shown the Hastings River estuary to have good water quality. Find out more about the estuary and its unique features.
Hastings River is located on the mid-north coast of New South Wales. It is a large barrier estuary with a permanently open, trained entrance.
The river and its estuary dominate the landscape and provide a focal point for Port Macquarie and surrounds. The Maria River and Limeburners Creek converge with the lower estuary, the latter supports extensive important wetlands and other significant habitats.
As part of our water quality monitoring program we assess the water quality and ecosystem health of an estuary using a range of relevant indicators. We sample a subset of the estuaries located between the Queensland border and Taree every 3 years. The most recent sampling in the Hastings River was completed over the 2018–19 summer when 2 sites were sampled on a monthly basis.
This report card represents 2 water quality indicators that we routinely measure: the amount of algae present and water clarity. Low levels of these 2 indicators equate with good water quality.
The report card shows the condition of the estuary was good with:
Port Macquarie–Hastings Council in collaboration with the University of New England’s EcoHealth program have carried out detailed ecosystem health monitoring in the Camden Haven River. The results of the monitoring program, including a detailed water quality report card, are available on the Port Macquarie–Hastings Council website.

We have monitored water quality in the Hastings River since 2007. This table shows the water quality grades for this estuary over that time.
Grades for algae, water clarity and overall are represented as:

Around two-thirds of the Hastings River catchment remains as forest, and much of this lies in the upper catchment. Most of the middle valley area supports beef and dairy production, with grazing making up about one quarter of total land use. The lower valley contains more rural-residential and urban development. The largest township in the catchment is Port Macquarie, situated adjacent to the river mouth.

The Port Macquarie bar crossing web camera provides real-time video of conditions within the river entrance immediately offshore to help with bar crossings and boat safety.
The NSW Food Authority website lists the current status of oyster/shellfish harvest areas.
Local councils manage estuaries within their area unless the estuary is attached to a marine park. Port Macquarie–Hastings Council manage this estuary. Resources can be found on their waterways and coastlines webpage.
The Hastings River estuary supports an endangered ecological community, lowland rainforest on floodplain, which provides habitat for the red-legged pademelon.
