Given you are half a world away, and I have never been there, I don‘t know what you would have for natural soils and flora, but there is an easy way to get Mycos and other beneficial micros in your soil.
If you have forests nearby, take a container into the forest with you and gather some soil (handful from different spots), leave litter, roll a fallen tree over so you can access the rot and soil underneath and take a handful of what you find there. Lastly, pull up a few small but older plants (roots and all) and throw them in your bucket too.
All these things will have beneficial: bacteria, fungus, nematodes and some mycorrhiza in it that will inoculate your soil and multiply as they break down the organics. The plants you pull, lay them out to dry. As the roots die, if they have mycorrhizae (which they likely will), it will die with the roots but will form spores before it dies. You can break the dried roots up, put some in your soil and also a bit in each hole before you plant. As the roots from you plant come in contact with these spores they will inoculate the roots.
Most of these micros we add to our soil are easy to get in the wild, but most people either don‘t have access (city folk) or can’t be bothered to go out and collect it
On another note, after you harvest your plants, leave the roots in the soil and let them die and decompose there, all the mycorrhizae that had infected your roots will die off forming spores again for the next plant that comes along
