In May 2025 the Manning River rose 3.55 metres above its May average at one gauge, a record. Matt and Peita Carroll lost about half a million Sydney rock oysters and put their first damage estimate at around $250,000. Ian Crisp lost $100,000 of baskets and a $40,000 grading machine.1

Two Entrances

The Manning is a double delta, described as the only river of its kind in the Southern Hemisphere. Its southern mouth, Farquhar Inlet near Old Bar, is usually closed by a sand bar. The flood, helped by a notch cut by Mid Coast Council, opened it.1

For growers that matters more than the losses. With sea water coming in through both mouths, salt returns faster after rain. Rose Crisp put it this way: "Your oysters aren't stressed for as long." Matt Carroll, who is president of the growers' association, expects the benefit to last up to five years. The council has costed keeping the entrance open by dredging at about $30 million over 20 years and judged it not viable.1

Flavor Breakdown

The water
A large river with a long tidal reach. Salinity swings with the rain, and our scores put sweetness at four and brine at two.
The finish
Earthy and savory. After a wet season expect a softer, sweeter oyster; after a dry one, more salt.

What Makes Manning River Unique

Few oysters depend so directly on whether a sand bar is open. About a dozen growers work the river, in an industry worth just over $1 million in 2023–24.1
