Certified GKH Gardening Expert
We are based in the US so I am not quite familiar with your climate and native Flora. A quick research has led me to the fact that your climate is quite mild, and has a wet and dry season.
You will do best to use tropical, or warm types of plants, and focus on those that can handle lots of water.
You will need to water during the dry season, and leave them in the wet season. It is much easier to add water when there isn't enough than to remove water when there is too much.
These plants could be suited for your area: https://www.gardeningknowhow.com/special/tropical/tropical-gardening.htm
