Hi firsthomwbuyer25
You have a class "p" due to the depth of clay fill on site.
Your house was built during a drought which was the second halve of 2015 followed by a mini wet period.The soil around that estate has highly reactive soil.You are very close to several old volcanoes.The fill used in your area is from highly reactive clay and going by your logs shows it was on the dry side.If the builder didn't use temporary downpipes and grade the soil away from the footings then you have all the factors that can lead to slab heave.
Eynesbury and the Melton area have had their fair share of slab heave
Highly reactive fill can swell more that similarly reactive soil in its natural state.
Once it has happened what to do about it is a difficult question.

I’m starting to think that there were some issues around the construction phase. Here’s some photos that I’ve got. There is a fair bit of spill from the slab being poured.

The cladding on and no stormwater system was even installed as you can see it under the back deck and the spouting ran straight to alongside the slab (house was built in wet period) soil was not graded away.

The downpipes are not connected in the middle photo and I can't see any stormwater entry pipes sticking out of the ground.
Was there an issue with the plumbing after the initial plumbing was installed pre slab?What are all the pvc pipes doing there under the pergola?
The builder has not graded the soil away from the house which they are required to do in AS2870.
