Loose Concrete Panel at Meacher Street, North Mount Druitt -Tripping Haard For The Community!

Here is a concrete slab, that has gone loose in Meacher Street, North Mount Druitt.

I'm not to sure , who to refer to at this stage - but it has a "T" which  sis the old Telstra logo and I think it may be storing telephone or internet cables underneath. It based  East of the corner of Pierce Street and Meacher Street, North Mount Druitt. It appears to  be wear and tear rather than someone that has destroyed it. I think the concrete supporting the concrete slab. must have crumpled  to pieces.

You can see how the concrete slab lifts up easily

I'll try lodging a complaint through Telstra but if Blacktown City Council Officers can assist us that will be great.

Here is  details from telstra of the complaint:
