Before I came to Mauritius, I sold my house and almost everything I owned. I arrived with one very heavy suitcase and a backpack.
I reserved in a cheap Airbnb for three weeks while I looked for a place to rent.
I found a "furnished" flat within a couple of days. Furnished is an ambiguous term. My place had mattresses, a small dining table with chairs, a couch and coffee table, and a few dishes, etc.
As I started to make friends, it was obvious that my kitchen was under-equipped, so I bought a microwave, a rice cooker, an air fryer, a wok, a pan, and a pot.
Then I got a little carried away with buying stuff from amazon.com and importing it using myus.com (a package forwarding company which I highly recommend). I bought a desk, a billion dollars worth of anti-mosquito artillery, a dehumidifier that runs on diesel (yes, I'm joking), a Zero Water water filter that holds enough water to fill an Olympic pool*, and lots of little electronic things that light up and beep and plug into computers.
* Maybe I'll set up the dehumidifier to drain into the water filter. That would be genius.
Mauritius is a small place. The whole island is one quarter of the size of the county I used to live in. There are 1.3 million people here. If it were a city, it would rank as the world's 400th largest city (about the size of Prague). It's also far away from everywhere. That means the market for electronic things that light up and beep is fairly small. It has an abundance of truly beautiful beaches, but the parts God didn't make are a bit ramshackle. Incomes here tend to be low. If you are used to wealthy western economies, you'll immediately notice the limited variety and, perhaps more importantly, the dearth of high-end products. There are no Amazons, Costcos, or Walmarts, here. There are a few big stores in Tamarin, Phoenix, Trianon, etc., but if you're looking for a place to buy Mikasa plates and Cutco knives, you're probably going to be disappointed.
People here don't buy a lot of stuff they don't really need. Garage sales aren't really "a thing" here. There is also no serious equivalent to Craigslist.com or OfferUp.com.
If you are particular about your possessions, it will be cheaper and easier to bring them with you than to import them after you are here.
My rule of thumb is that shipping and duties will essentially double the cost of what you import, On top of that, there is a long, arbitrary list of things that customs will turn into torture. For example, I bought a kite. You know... for kids. I probably spent two hours dealing with import issues. I bought a USB Wi-Fi dongle for my computer: three more hours of misery. Mosquito attractant (for a mosquito trap)? Two more hours.
If you are content to make do with the generic stuff that is available on the island, leave it behind and replace it when you get here.
If you can't live without your bamboo sheets, Oneida flatware, and Jimmy Choo's, bring them with you. You won't find them on the island and they'll be very expensive (and often frustrating) to import.
