Data Inputs To Match As Generated From Geoscience Australia

Shadow Diagram Australia is typically prepared for mid-winter 21 June and Equinoxes at 9:00 AM, 12:00 PM 3:00 PM. In complicated projects, Council may require more hours than just 3 times of a day. We can provide a shadow diagram for a certain period of time and day upon request by the Council. By doing so, we can clearly demonstrate and answer any overshadowing and solar access concerns. Our service enables a flexible and fast shadow diagram that addresses all planning requirements for the Development Application Process.
We can determine the impacts of a proposal on the adjacent residential buildings and their private open space. Shadow Diagram Australia views and calculates the amount of shadow cast by the proposed development. It contributes in determining the shading effect of the adjacent structures as well as those casts by the proposed structure which helps in shaping the sustainability of the development.



  1. Mid-Winter at 9 am, 12 noon, and 3 pm (Standard)
  2. Mid-Winter with Elevations at 9 am, 12 noon, and 3 pm with elevations of adjoining premises*
  3. Mid-Winter and Equinoxes at 9 am, 12 noon, and 3 pm
  4. Mid-Winter and Equinoxes with Elevations at 9 am, 12 noon, and 3 pm with elevations of adjoining premises.*

*Council may require more hours – subject to additional fee.


  • In accordance with the survey (prepared by a registered surveyor) which is required to be submitted with the proposal.
  • Drawn to true – north
  • To indicate the shadow cast by existing buildings and structures on the site and the surrounding area; and
  • If applicable elevations of adjoining premises showing existing and proposed shadows.
  • Data parameter inputs to match with longitude, latitude, azimuth and altitude as generated from Geoscience Australia.
