native english speaker vs. non-native speaker

[ugyen]

Hello everyone from English speaking world.
I am interested to learn (if there is any difference) –looking at phonetic between:

native English speakers VS non-native speaker of the following counteries:

American English speaker and non-native speaker
Australian English speaker and non-native speaker
British English speaker and non-native speaker
New Zealand English speaker and non-native speaker

Thank you

Non-native speakers could speak any of hundreds of different languages and be at very different stages with English pronunciation, so I would say it is too broad a question to answer. Some non-native speakers are indistinguishable, but most do show differences.
