Bob, You could try Goat's milk and sheep cheese. In Ireland Goat milk is available in many large chains though about twice the price of cow milk.
Sheep cheese is available in many West and South Asian food stores.

Most cheeses are high in proteins so will have A1 if it's in the source milk used.

Also I'd not be complacent about UK, Aussie or Irish milk being A2. It's likely to be predominantly A1 unless stated otherwise.
Also, being of a suspicious nature, I'd suspect there's a strong possibility of some A2 labelled milk being contaminated with A1 given the large price premium.
