The full-circle camping trip is something most people don't bother trying — catch your dinner, cook it on the fire, eat it that night. It's not as hard as it sounds, and once you've done it once you'll do it on every trip after.

The trick isn't the cooking. It's everything you do before the cooking — how you handle the fish from the moment it hits the deck. Get that right and a $4 frozen fish from the supermarket has nothing on a flathead you caught at lunch and ate at sunset. Here's the practical version.

The single best rule for any angler. Just because you can legally take 10 fish doesn't mean you should — take what you'll eat fresh, and let the rest go to fight another day.

Bag and size limits matter. Every Aussie state runs its own fisheries app — NSW DPI Fishing, VIC Fishing, QLD Fishing 2.0, WA Recreational Fishing, etc. They're free, current and in your pocket. Open them BEFORE you put a fish in the esky, not after.

And only kill what you can eat that day or the day after. Fresh-caught beats frozen every single time.

If you're keeping a fish, kill it fast. Don't let it flap around in the bottom of the boat for 20 minutes — that's both cruel and ruins the meat (lactic acid builds up and the flesh deteriorates).

The standard method (iki jime):

• Hold the fish firmly
• Find the soft spot just behind the eye on the upper side of the head
• Insert a sharp spike (or sharp knife tip) cleanly into the brain
• The fish will visibly flutter then go still — that's it, done

Then bleed it: cut the gills with the knife and let the fish bleed into the water for 30 seconds before icing. This dramatically improves the eating quality.

For smaller fish a sharp blow to the back of the head with a small priest (a weighted club) is faster than the spike method.

The single biggest factor in fish quality is temperature. From dispatch to plate, the goal is to keep it as cold as possible.

• Have an esky with ice ready before you start fishing. Slurry-style ice (water + ice cubes) is faster than block ice for cooling fish
• Never leave fish flopping in the bottom of the boat in direct sun. Even 10 minutes hot will degrade the meat
• Don't store on the bank in a wet sack — that's a old myth that turns fresh fish into bait
• If camping, keep them whole and on ice in the esky until you're ready to fillet — usually that means scaling and gutting them right before cooking

A blunt knife is dangerous, slow, and wrecks fish flesh. Three knives cover everything:

• Long flexible fillet blade (15–20cm) — for skinning and filleting. The flex lets you ride the bone
• Short stiff blade (10cm) — for gutting and gilling. Stiffness matters here for control
• A small priest or iki spike — for the dispatch step

Sharpen them at home before the trip. A small ceramic rod or pull-through sharpener should live in the tackle box for touch-ups on multi-day trips. A sharp knife is safer than a blunt one — counter-intuitive but true. You apply less pressure, you control the cut.

Brands worth the money: Victory, Wusthof, Dexter-Russell. Avoid the $5 "fishing knives" at servos — they're stamped steel that won't hold an edge.

For smaller fish (whiting, bream, garfish, small tailor, panfish), filleting is wasteful. Just:

• Scale
• Gut and remove the gills
• Wipe out the bloodline along the spine
• Cook whole

For bigger fish, cut into steaks across the spine after scaling and gutting — bone-in, skin-on, way more flavour than fillets.

Wrap whole fish or fish steaks in foil with lemon slices, herbs, butter and a splash of white wine. Throw on the BBQ grill or directly into hot coals for 15-20 minutes depending on size. Eat directly from the foil. Few meals beat it.

Whole fish in foil (the default) — Scale, gut, score the sides 3 times each side. Stuff the cavity with lemon slices, parsley, garlic, salt, pepper, butter. Wrap tight in two layers of foil. Cook on coals or BBQ grate, 8 minutes per side for fish up to 1kg.

Beer-battered fillets — Mix a cup of self-raising flour, a beer, salt, pepper into a thick batter. Heat oil 2cm deep in a cast iron pan over medium coals. Dip fillets in flour, then batter, then straight into the oil. 2-3 minutes a side until golden. Eat with chips and lemon.

Fish on coals (the bushman method) — For bigger fish: scale and gut, brush with oil, throw the whole fish directly onto a bed of red coals (no foil). Sounds destructive, isn't — the skin chars and protects the flesh. Cook 4-6 minutes a side, peel off the burnt skin, eat the flesh underneath. Genuinely the best way to cook a freshly caught fish if you trust your fire.

• Fish tastes "muddy" — usually a freshwater carp or trout caught in stagnant water. Bleeding it properly + cooking same day prevents most of it. Soaking fillets in milk for an hour before cooking also helps
• Flesh is mushy — fish wasn't bled, was kept too warm, or sat too long before cooking
• Skin sticks to the foil — oil the foil before wrapping, and let the parcel sit for 2 minutes after cooking
• Bones everywhere — for very bony fish (mullet, garfish), score the flesh deeply on both sides before cooking. The bones soften and become edible after high heat

Catching and cooking your own dinner is one of those camping rituals that becomes addictive. Once you've eaten a flathead you caught yourself two hours ago, supermarket fish loses its appeal forever.

Three things to nail: keep it small (don't over-keep), keep it cold (slurry ice in the esky), keep it sharp (decent knives). The cooking is the easy part.
