My house is nearing completion, and I've just noticed this area of the slab where styrofoam is showing through.
How big of an issue is this? Or is it an issue at all? (Really hoping it's no big deal as this build has already had so many delays)

Edit: contacted the builder who reckons its a bit of "boxing". Not sure what that means though?
Styrofoam showing through foundation slab, how bad is this?

Styrofoam when left open to the weather and sun deteriorates very quickly...

Yeah it looks like a waffle slab. It needs to be rectified ASAP and ask the builder to ensure that the soil around the perimeter of the house are graded away from the house.
If not, it could cause slab heave.

this shouldn't happen. The boxing is a Styrofoam waffle pod used to form the "waffle" pattern of the slab under the main part. There should be something like a 85-100mm thickness of concrete between the outside and the pods. Probably more here as its the rebate that the bricks are laid on. Kind of concerning. begs the question of how sound the rest of the slab is.
