It is similar but not the same. Australian or American is a slang but still English as standard. There are no standard for bahasa. In order it to be an official language, you need to choose one.

Which ties back to my original question, what would Indon say when you with only 32mil speaker want to use your bm as standard instead of b. Indon which have 280 million speaker? Indons are very patriotic too.

It's just silliness and would go no where while offending our neighbours.

Got minor difference. Like spelling and some words commonly used like boot/trunk and bonnet/hood or pants/trousers lift/ elevator
