Aside from Great Britain? Canada, Australia, and New Zealand.
There's a whole lot more than three, and you didn't specify whether you meant Commonwealth Dominions (who acknowledge the British monarch as their own Head of State), or Commonwealth of Nations members (to whom the British monarch holds no status, but with which trade an other agreements exist with the British). Three Commonwealth Dominions include Canada, Australia, and Barbados. Three Commonwealth of Nations members who are not Dominions include South Africa (for better or worse), India, and Singapore.

King Edward VII, King of the United Kingdom and the British Dominions, Emporer of India.
The British Empire comprised the dominions, colonies, protectorates
Canada, Australia, and New Zealand.
The Statute of Westminster, enacted in 1931, involved the British Parliament and the self-governing dominions of the British Empire, including Canada, Australia, New Zealand, South Africa, and the Irish Free State. It was a significant legislative measure that granted these dominions legislative independence and the ability to make their own laws without British interference. Key figures in its development included British Prime Minister Ramsay MacDonald and various leaders from the dominions who advocated for greater autonomy. The statute marked a pivotal moment in the evolution of the British Commonwealth and the relationship between Britain and its former colonies.
The three dominions of life are Bacteria, Archaea, and Eukarya. Bacteria and Archaea are both prokaryotic domains, while Eukarya consists of organisms with eukaryotic cells, including protists, fungi, plants, and animals.
It was one of the Dominions of the British Empire, and therefore committed to defending the interests of the UK.
Neither New Zealand or Australia are "dominions of England". Both are independent countries, with a parliamentary democracy. There is The Commonwealth, which is composed of many of the former members of the British Colonies, but not all Commonwealth members are ex British colonies, nor are all ex-colonies members of The Commonwealth.
Nationalists, Unionists and the British Government.
They do have a connection to the British Empire - so much so, that they're even one of the 16 Commonwealth Dominions which acknowledge the British Monarch as their Head of State.
