Fish worth a million dollars are typically rare, high-quality bluefin tuna sold at Japan's New Year auctions for prestige and good fortune, or exceptionally rare Japanese koi bred for unique colors and patterns, with recent sales reaching over $3 million for tuna and $1.8 million for koi. These prices reflect cultural value, culinary demand, and the fish's status as a collector's item rather than just food.
In 1955, C. Leslie Griffith captured a 7.5-foot, 181-pound white sturgeon near Dayton. The massive fish was displayed at the Polson-Flathead Historical Museum and fueled theories that sturgeon — rare, deep-dwelling, and prehistoric-looking — might be responsible for the sightings.
The Fisheries Act 1902 (NSW) ( DOC0358 ) recognised Aboriginal fishing by exempting Aboriginal people from certain regulations. It expressly permitted Aboriginal people to take undersized oysters from public oyster reserves, as well as undersized fish, provided they were mature enough and for personal consumption.
A 50cm flathead's age varies, but for a common Dusky Flathead, it's often around 4 years old, though it could range from 1 to 7 years, with females generally growing faster and larger than males. For Sand Flathead, reaching 50cm might mean it's around 16 years old, highlighting different growth rates between species.
Yes, Murray cod is considered excellent eating—a premium freshwater fish with mild, sweet, white flesh that's firm and flaky, juicy, and holds up well to various cooking methods like steaming, grilling, or pan-frying, offering a clean taste and good health benefits from its fatty acids.

Hoki and flathead are popular white fish for eating, but differ in flavor, texture, and sustainability: Hoki is affordable, mild, flaky, great for fish & chips (often imported), while Flathead offers a sweeter, more delicate taste, firm texture, and is prized (especially local varieties like Rock Flathead) but pricier and sometimes less sustainable depending on origin, with Rock Flathead often a top sustainable choice in Australia.
Low oil content with a pleasant, sweet flavour. Fine textured flesh which can dry out slightly with some cooking methods but remains moist and flaky when cooked in batter. The long shape of flathead means that it fillets well as most of the bones are at the head section of the fish.
In NSW you're allowed to keep one flathead over 70cm. At that size the fish will generally be a mature breeding female that can potentially lay hundreds of thousands if not millions of eggs annually.
But, the average bass should grow between 5 – 20cm in the first year. Within 2 years they will reach an adult length of 25 – 30cm. It is possible to increase the rate of growth by feeding your bass a protein rich diet.
Recreational Fishing Licence Fee – exemption

A 30cm bream, particularly species like black bream, is typically around 8 to 10 years old, as they are slow-growing fish that often reach this legal minimum size after nearly a decade, with some studies suggesting it takes about 9 years to reach 28cm. Older, larger bream can be significantly older, with fish over 40cm sometimes being 14 to 18 years old or even older.
The standard three-part test for Aboriginality in Australia requires a person to meet three criteria: descent (biological ancestry), self-identification (identifying as Aboriginal or Torres Strait Islander), and community acceptance (being recognized as such by their Indigenous community). This definition, adopted by the Commonwealth government, is used for many government programs and services, although the Australian Bureau of Statistics (ABS) uses a simpler two-part test (descent and self-identification) for general data collection.
