Welcome to the Bunnings Workshop community @yana. It's fantastic to have you join us and many thanks for your question.
You might like to start by reading How to build a simple raised garden bed or for something a little more advanced How to build a raised garden bed by @Adam_W. Adam goes into detail about what materials to use and how to assemble the garden beds. I trust you'll find both articles very useful.
You'll need timber suitable for in-ground use which is typically H4 treated pine. It appears you are looking for an alternative to traditional CCA treated timber, the Micropro Sienna sleeper range would be a suitable option. There are limited options when it comes to posts with a non-CCA treatment. I would suggest you either use the Whites Retain-iT system or sleepers for the posts as well. Both of these methods are described in Adam's articles.

Microshades are awesome, no need for any lining just screw them together and away you go, hardwood is fine also
hardwood posts easy as, and or use gal brackets to keep them together
As has been said Microshades sleepers are excellent and considered 'safe'. That's what I use in al of our food garden beds here at home.
Hardwood, if you can find it untreated, is also excellent but harder to cut & lift etc. Be aware that a lot of hardwood is CCA treated so look carefully at product details. Some peopel will suggest recycled railway sleepers. I would advise against that. Apart from being crazy-hard to work with they can be heavily impregnated with all manner of industrial grade chemicals.
