Steak is where most Australians judge their barbecue skills, and the good news is that consistent results come from science, not luck. A steak cooks from the outside in: the grill sears the surface, heat conducts toward the centre, and the final internal temperature decides doneness. Master the heat transfer — sear hard, finish gently, rest properly — and a $25 steak from the supermarket will eat like a $50 steak from a steakhouse.
Choosing Your Steak
In 2026, supermarket beef prices sit roughly at $25–$35/kg for rump, $35–$45/kg for scotch fillet, $45–$60/kg for eye fillet, and rump cap is regularly promoted under $30/kg on special — the rump cap (also sold as picanha) is the best value steak in the supermarket because it has the marbling of a much more expensive cut. Grass-fed Australian beef is leaner than grain-fed beef, so it suits medium-rare to medium; take grass-fed past medium and it dries out quickly. For BBQ, buy steaks at least 2.5–3 cm thick — thin steaks are impossible to sear and finish properly without overcooking. Scotch fillet (rib eye) gives the most forgiving ratio of fat to meat; rump is leaner and needs care; eye fillet is tender but low in fat, so it rewards a quick hot cook and nothing more.
Preparation
Take the steak out of the fridge 30–45 minutes before cooking so the centre is not ice-cold — a cold centre is the main reason steaks end up grey outside and raw inside. Pat it dry with paper towel: moisture on the surface has to boil off before browning can start, and steaming the surface is how you get a grey, stewed crust instead of a sear. Season generously with salt (about 1 teaspoon per side for a large steak) just before it hits the grill, or salt 40 minutes ahead and let it draw moisture back into the meat — the choice is yours, but salt is not optional. Oil the steak lightly, not the grill bars.
Doneness Temperatures
Internal temperature is the only reliable doneness test. For Australian grass-fed beef, target: rare 50–52°C (cool red centre), medium-rare 54–56°C (warm red centre — the sweet spot for most cuts), medium 60–63°C (pink band), medium-well 65–68°C (barely pink), well done 70°C+ (no pink). Pull the steak 2–3°C below your target because carryover cooking keeps raising the temperature during the rest. If you do not own a probe thermometer, buy one — a reliable instant-read model costs $30–$80 and removes all guesswork.
Cooking Times (approx. per side on high heat)
These are starting points for a 2.5–3 cm steak on a preheated grill at 220–250°C, cooked direct: rare 2–2.5 minutes per side, medium-rare 3–3.5 minutes, medium 4–4.5 minutes, medium-well 5–5.5 minutes. Thicker steaks (4 cm+) need a different approach: sear 90 seconds per side, then move to the indirect (cool) zone with the lid down until the probe hits your target. Every grill runs differently, so treat these as guides — the thermometer is the boss.
The Perfect Sear
A good sear is Maillard browning: the surface reaches roughly 140–160°C, amino acids and sugars react, and hundreds of flavour compounds form. That reaction needs a dry surface, high heat and contact. Flip the steak every 60–90 seconds rather than leaving it untouched — frequent flipping cooks more evenly and builds the same crust with less risk of burning. If flare-ups engulf the steak, move it to the cool zone for a few seconds rather than spraying water on the coals or flame.
Resting
Resting is not optional. During cooking, heat pushes moisture toward the centre; resting 5–10 minutes (loosely covered with foil) lets the muscle fibres relax and the juices redistribute evenly through the meat. Slice immediately and you lose a pool of juice on the board — rest properly and that juice stays in the steak. For thick cuts, rest in a warm spot, not on a cold bench, and never rest under tight foil for more than 10 minutes or the crust softens.
Serving Suggestions
Slice against the grain — across the muscle fibres — so each piece is easy to chew. Serve with the classic Australian sides: a fresh salad, potato bake or grilled vegetables, and a sauce that complements rather than drowns the meat — chimichurri, red wine jus or a simple mustard. In New South Wales and Victoria, the steak-and-salad plate dominates; in Queensland, steak often arrives with a baked potato and sour cream; in South Australia, a peppery sauce is the default. Any of them work, as long as the steak itself is the star.
Actionable Steps
- Buy thick (3 cm+) cuts — rump cap on special under $30/kg is the value pick of 2026.
- Rest the steak at room temperature, dry it, salt it, oil it.
- Preheat the grill fully, then sear 60–90 seconds per side, flipping often.
- Cook to 54–56°C internal for medium-rare, pulling 2–3°C early.
- Rest 5–10 minutes, slice against the grain, and serve.
