I live in the desert too, but in the US.
Not familiar with creatures in your part of the world, but I would venture to guess they are not much different or more venomous than what we have where I hike. Snakes are mostly nocturnal and are more afraid of you, than we of them. With a few exceptions, most scorpions in deserts are not deadly.
Given that, I never sleep in a tent or tarp if it is not raining or the rare snow storm.
Occasionally I will set up a shelter in wind.
My current go to shelter is a zPacks Hexamid solo. You can get a 1 oz carbon fiber pole from zPacks too, but it is quite flimsy. I purchased a much sturdier pole from Bocca Lutura (sp?) at 3 oz.
But if you prefer an enclosed shelter look at zPacks, Mountain Laurel Designs, Six Moons Designs, and Tarp Tent. I have dealt with all these companies and they make quality UL shelters.
