@diabolika, sending you the best of wishes as you move to your new place.
I love seeing your tropical, eco-paradise. Every time I see photos of your adventures it reminds me of my time overseas.
You can probably find banana trees naturally where you live, but if you find a variety that you enjoy I recommend replanting close to your house.
I am not sure about the rules where you live, but in Indonesia foreigners could not own land. I recommend that you find out about laws related to land ownership. I wouldn't want your eco-paradise plans to be derailed.
Thanks, @sumatranate! Yes, there are banana trees around here! Maybe I can plant close to my place too.
I'm pretty sure I can buy a land here... I only need cash hehe.
