T continue Sir H’s reasoning, this is what the “who’s Responsible” document says:
If they (fences) are shown as a thick line on the strata plan then they are deemed a common wall and the responsibility of the owners corporation.
However, if they are shown as a thin, dotted or no line on the strata plan then they are treated in accordance with the Dividing Fences Act and are treated as follows:
1. Divides two lots. Each owner is responsible 50/50
2. Divides one lot from common property. The owner is responsible 50% & the owners corporation is responsible 50%
3. Divides one lot from the adjoining property. The owners corporation are responsible for 100% of its share
