Short answer — several widely‑available labels sold in Australia specifically advertise grain‑free dog recipes. Notable examples include:

• Ivory Coat — markets a dedicated "Grain Free" range (dry and wet formulas). (ivorycoat.com.au)
• Black Hawk — has multiple grain‑free adult and puppy recipes (chicken, kangaroo, salmon, etc.). (blackhawkpetcare.com.au)
• ACANA — many ACANA recipes are labelled grain‑free / "no grain ingredients" (sold in AU). (apac.acana.com)
• ORIJEN — sold in Australia and promoted as biologically‑appropriate, grain‑free formulas. (mypetland.com.au)
• Taste of the Wild — commonly sold in AU as a grain‑free range (several flavours). (myrainbowpets.com.au)
• ZIWI Peak — air‑dried and wet recipes that are explicitly grain‑free. (ziwipets.com)
• Prime100 (PRIME100 SPD / Prime100 SPD Air‑Dried) — Australian brand with grain‑free / zero‑grain air‑dried and dry formulas. (petso.com.au)
• Pure Life — Australian made brand that offers a grain‑free "Natural Boost" range (kibble + freeze‑dried boost). (purelifepetfoods.com.au)
• K9 Natural — New‑Zealand brand widely stocked in AU; freeze‑dried/freeze‑dried and canned products described as grain‑free. (au.k9natural.com)
• LifeWise — Australian brand that offers specific grain‑free recipes. (adspet.com.au)

A couple of quick notes:

• "Grain‑free" labeling varies (some brands have wholegrain and grain‑free lines), so check the pack/website for each recipe. (ivorycoat.com.au)
• Veterinary guidance: grain‑free diets aren’t automatically healthier for every dog — if you’re switching for a suspected allergy or another health concern, check with your vet first. (hillspet.com.au)
