Mr Inspector, a qualified building inspector conducts building inspections around Melbourne and the above photograph was taken during a building inspection in Aspendale. It shows a broken storm water pipe.

It is likely that it was damaged during construction and not replaced.  Technically a major defect due to the potential of further problems arising, it is relatively easy to rectify and should be fixed as soon as possible to avoid potential footings settlement.  A licensed plumber should be engaged to repair the damage so no excess water gets into the homes footings.
