Starting soil

Hi all, I’m thinking about starting a small-ish Terrium but I’m not entirely sure what I could get away with soil wise. I’ve had a quick look online and TikTok was the inspiration for getting started.

I reside in New Zealand so I’m not sure if I can get the different ‘soils’ that the internet suggests due to our somewhat stringent bio-security regulations, but I’m curious if this one would do the trick just in case we don’t have the perlite or coco coir / peat moss in NZ..

I’m sure we do have the necessary soils in other parts of NZ, but if I wanted to start tomorrow, would something like this work or would I need to wait to get the others? Also I’m keen on joinery / carpentry so would some of my wood chips / saw dust work as drainage as opposed to using stones?
