Indonesians, what is this language? The way they talk is so similar to native Fijians wtf?

I know native Fijians had ancestors that came from SE Asia but this sounds uncanny

It's less about the words themselves but more about the rhythym, tone etc. It's so strikingly similar to how Native Fijians speak wtf
