What building in Secret Harbour actually involves
Secret Harbour is coded R5 to R80 and carries a split code, R20/40/80 — the only three-way split we have published anywhere. It also maps both Residential and Development zones across 6.5 km².
A three-way split code is a condition, twice over
R20/40/80 means the applicable density depends on which conditions in the scheme or structure plan are met. It is not a menu. Establishing which tier applies at your lot is the first question, because the difference between R20 and R80 is a fourfold change in density and with it the lot size, setbacks and open space requirement.
Three structure plans, and development land
Three endorsed structure plans apply, and the Development zone marks land still in the pipeline. The plan covering your lot sets its density, layout and staging — in a suburb this new, that document does more work than the scheme map.
Bushfire on coastal heath
Part of Secret Harbour is inside a designated Bush Fire Prone Area. A Bushfire Attack Level assessment applies to a block inside one, and the rating changes the external construction specification.
What to ask a builder
Ask which R-Code applies and, if it is the split code, which tier and on what condition. Ask which structure plan governs. And ask what BAL rating is priced in.

Questions about building in Secret Harbour
What does the R20/40/80 split code mean?
The applicable density depends on which conditions in the scheme or structure plan are met. It is not a menu — establishing which tier applies at your lot is the first question, and the range is a fourfold change in density.
What R-Code applies in Secret Harbour?
Codes from R5 to R80 are mapped, including the three-way split code R20/40/80 — the only one we have published anywhere.
What is the Development zone doing here?
It marks land still in the development pipeline. The endorsed structure plan covering it sets density, layout and staging, and in a suburb this new that document does more work than the scheme map.
Is Secret Harbour bushfire-prone?
Part of it is inside a designated Bush Fire Prone Area, reflecting coastal heath. A block inside one needs a Bushfire Attack Level assessment, and the rating drives materials and cost.
Which structure plan applies to my lot?
Three are endorsed across the suburb. Your builder should be able to name the one covering your lot before quoting, because it sets the density and the layout.
