Top practical tips

Use two-zone heat: direct for quick sear, indirect for thicker fillets. Prawns: 2–3 minutes per side. Whole fish: 6–9 minutes per 2cm thickness. Shellfish: watch for open shells.

Prioritise sustainably caught local fish: flathead, barramundi, snapper, eastern king prawns. Ask your fishmonger for day-catch and condition.

Light olive oil, lemon zest, sea salt and white pepper for most fish. For prawns try chilli, garlic and lime. Finish with fresh herbs and a splash of native finger lime caviar when available.

Buy from reputable sellers, keep chilled on ice, and cook oysters or mussels until shells open; discard any that remain closed. In AUS, follow local NSW health advice during blooms.

Flakes easily with a fork and is opaque through the thickest part. Use a probe thermometer: 63°C (145°F) is a common target for many species.
