Here are Australian-available cat food brands that explicitly advertise high‑protein / high‑meat formulas (with a brief note on the product claims or guaranteed analysis):

• Ziwi Peak — markets “high meat” / high‑protein air‑dried, canned and dry recipes (many recipes list very high meat content / “high protein” on product pages). (myrainbowpets.com.au)
• Orijen — promoted as “biologically appropriate” with very high animal‑protein levels (Orijen cat formulas cite ~40% crude protein on many product pages). (petso.com.au)
• Feline Natural — New Zealand brand sold in Australia; repeatedly advertises “98% high protein” whole‑meat freeze‑dried, canned and pouch recipes. (au.felinenatural.com)
• Black Hawk (Australian) — advertises real‑meat first ingredients and some formulas described as “high protein” (example analyses show ~32% crude protein on adult recipes). (blackhawkpetcare.com)

Other brands often found in Australia that offer higher‑protein lines (worth checking specific product labels): Applaws, Fussy Cat / Nulo, Purina Pro Plan (select formulas marketed for performance), Hills/Science Diet (some “high protein” therapeutic or performance lines). Always check the guaranteed analysis on the pack (crude protein % on an as‑fed or dry‑matter basis) because “high protein” marketing can vary by formula and by whether values are given on an as‑fed or dry‑matter basis.

If you’d like, I can:

• look up protein percentages for specific formulas (e.g., Orijen Original, Ziwi Peak air‑dried, Feline Natural canned) and compare them on a dry‑matter basis, or
• find where each brand is stocked in Australia (petstores/online retailers).
