I’ve travelled a fair bit (Australia, NZ and South east Asia) and came accross some amazing places I could quite easily live. The east coast oz is amazing but can be fairly expensive.
I visited some Islands in Thailand, Malaysia and Phillipines and they were stunning, but running a business out their might be a bit more dificult i.e. getting a stable internet connection and even 24/7 electricity.
Ideally I would live somewhere in South east asia area (probably Malaysia) as I love the region and the £ goes a long way 
(and it’s closer to Macua)
