Hi I have googled a bit for soil tests in Australia and they are usually $110 each (it is a home garden)
But I have found this lab: https://www.csbp-fertilisers.com.au/docs/default-source/our-land-pdf/soil-pricelist-2016-17.pdf?sfvrsn=d292633e_0
what do your think? Is it a comprehensive test? And it is in WA I am in the Sydney region  far away.

Wow...if I did currency exchange correctly I come out with $82 for a soil sample, something that just cost me $12 here!!

Here we get a "standard" test and a "comprehensive test", the latter of which just contains the available nitrogen in the soil. The latter is of no great use unless it is in the midst of the growing season. For instance, I just took a soil sample, and because I live in the Northern Hemisphere; we just started the growing season so no real need for available nitrogen, so I got the standard test. But last year when I had a soil taken in August as I had a field that was in rough shape; I had the comprehensive test done.

For you; being in the southern hemisphere and in autumn, you can get by with one of the cheaper tests I would think.

The comprehensive test looks pretty good and is the one I would choose. Knowing the calcium levels along with the other cations they mention like magnesium is extremely helpful in building healthy soil. Calcium alone is so important for plant metabolic health, not to undermine the importance of other elements, but calcium is also what keeps soil clay particles from sticking together improving a soils ability to breathe and allow water to flow through. On the opposite side, excessive magnesium makes soil clay particles stick together and prevent soils from breathing and allowing water to flow. Having adequate amounts of elements in a soil is important, and part of it, but a lot of science has been gained in the last couple decades with a new understanding that proper ratios between certain elements, like calcium & magnesium, really makes soils thrive. Since the comprehensive analysis tests for both of those, you will have the values to help guide you to an ideal Calcium:Magnesium ratio of 10:1. Hope this helps!

Prices are good for Australia.
I really like their individual test prices, that allows you to get Exchangable cation concentrations for some of the primary minerals.
The comprehensive set is good but if you added this "Exchangeable Cations without pre-wash (Calcium, Magnesium, Sodium, Potassium, Aluminium)
cost minus GST 14.95  cost w/GST 16.45  sample size required 15g", you would have a really good set of information.

Don't forget that silicon is a required mineral for micro organisms to be able to utilize calcium, iron and other important micronutrients, all of which will build you great soil.

Yes our prices (of everything) are through the roof. Thanks for the hint with the silicon.

Through the roof?
I just got one done and that was the cheapest I could find. I paid C$160. I had quotes last year that were in the $350-400 range.
What I am doing wrong?

Simone, you might try to get in touch with this part of the Canadian Government, they might still have an extension service with lower prices on soil testing.
