Hello @Mooney69
Welcome to the Bunnings Workshop community. It's marvellous to have you join us, and thank you for sharing your question about a base for your shed.
There are a few options such as building a timber frame, using large heavy pavers and making a concrete slab. Among the three only building a concrete slab gives you longevity and a viable anchor point for the shed. With the local council rules in mind, a shed must be anchored properly to prevent it from blowing away in a storm. Timber as you know deteriorates faster and is not as long-lasting as concrete. Pavers on the other hand tend to spread out and let water in making your shed very damp inside.
If this is a long-term investment, I recommend using Bastion 20kg Concrete Mix to build your slab. From a cost point of view building a concrete slab is a good way to protect the items in your shed because you can seal the bottom of the shed to the concrete floor.
