Here are Australian pet-food companies (and Australian-made ranges) that advertise or promote “holistic” / natural / raw nutrition for cats — with a short note on what they emphasize:

• Black Hawk — Australian-made natural/holistic cat range (grain‑free, real Australian meats, no artificial colours/flavours). (blackhawkpetcare.com.au)
• Ivory Coat — Australian brand that promotes “raw-inspired” natural nutrition for cats (freeze‑dried raw toppers, superfoods, probiotics, Australian‑sourced ingredients). (petbarn.com.au)
• Big Dog Pet Foods — Australian raw / BARF range that includes complete raw diets for cats (promotes evolutionary/raw nutrition). (bigdogpetfoods.com)
• Meals for Mutts (MfM) — Australian‑made brand that markets “holistic” and hypoallergenic cat foods (natural ingredients, grain/gluten‑free options). (mealsformutts.com.au)
• Evolution Pet (Australian Holistic range) — an Australian‑owned range explicitly labelled “Australian Holistic” for cats (grain‑free / no artificial colours, focused on wellbeing). (evolutionpet.com.au)
• Nature’s Gift — Australian brand/line positioned as a natural/feline formula (promotes natural ingredients and complete nutrition). (apfe.com.au)
• Optimum (Australian range) — marketed in Australia as a natural/complete range (no added artificial colours/flavours; emphasis on balanced, whole‑food nutrition). (petservo.com.au)

Notes:

• This list isn’t exhaustive; many smaller local raw/holistic makers and specialist raw suppliers also operate in Australia (and several overseas “holistic” brands are widely sold here).
• Product formulations and brand ownership can change, so check the specific product pages or packaging (and, if your cat has health issues, consult your vet) before switching diets.
