Hi @Jimi77,
A warm welcome to the Bunnings Workshop community and thank you for your question.
My advice would be to remove a small amount of the soil, add a layer of road base, and compact it with a tamper. Check out How To Prepare And Lay a Base For Pavers for some guidance on foundation prep.
You can then lay your pavers on top using paving sand or mortar as a levelling material. Check out How To Lay Pavers for guidance on this step.
Let me know what you think and if you have further questions, please don't hesitate to ask.
Jacob
