Here are Australian (or widely-available in Australia / ANZ) cat-food brands known for focusing on natural ingredients and marketing “no additives” or minimal processing. I’ve listed what they commonly claim so you can check labels for the specifics that matter to you.

Brands

• Feline Natural — high‑meat wet, canned and freeze‑dried recipes made from wholefood ingredients, marketed without gelling agents, fillers or artificial additives. (au.felinenatural.com)
• Black Hawk — Australian brand that promotes real Australian meats as primary ingredients and recipes “with no artificial preservatives, colours or flavours.” (dry and wet options). (adspet.com.au)
• Frontier Pets — Australian-made natural cat food brand emphasising free‑range meats, organic veg and “no artificial additives, preservatives or synthetic chemicals.” (frontierpets.com.au)
• Meals for Mutts (MfM) cat range — markets its cat food as “all‑natural” and explicitly states free from GMOs, preservatives, additives and artificial flavourings. (mealsformutts.com.au)
• HealthyKitty (Australia) — small Australian producer claiming grain‑free, “no additives or fillers, no preservatives, no artificial colours or flavours.” (HealthyKitty.com.au)
• Ziwi Peak (NZ, widely sold in AU) — air‑dried and canned recipes high in meat content and minimal processing; marketed as wholefood, limited‑ingredient recipes (good to check each formula). (au.felinenatural.com)

Quick buying tips

• Read the ingredient list: look for named meats (chicken, beef, fish, kangaroo) near the top and short, recognisable ingredients.
• Watch for wording: “no artificial colours/preservatives/flavours” is different from “additive‑free” — check what preservatives are used (e.g., mixed tocopherols are natural vitamin E antioxidants).
• Check guaranteed analysis and AAFCO/NFSA (or local) statements for “complete & balanced” if you want a sole diet.
• If your cat has allergies/sensitivities, look at limited‑ingredient or single‑protein ranges and consult your vet before switching.
• Smaller local brands sometimes offer fresher, minimally processed options but can vary between batches — check reviews and label transparency.

• Compare ingredient lists for 3–4 specific products you’re considering, or
• Find retailers in your region stocking any of these brands (I’ll check availability/pricing).
