Hi everyone!
New home owner here with a fresh build. Our nature strip has been somewhat destroyed by a skip and building material that occupied the nature strip for much of 8-9 months. Just looking for some suggestions on the best course of action is from this point in time. Photos attached below of the initial state with dead grass and concrete.

Currently I've raked and shovelled a lot of the building materials/stones and contaminating materials from the top of the surface, leaving an "okay-ish" looking soil. I'm hoping it's salvageable from this point and not a complete replacement of soil etc.
Any updates regarding soil/seed/fertilizer options would be great and for reference we're in the south east Melbourne area.
