How Blue Bay is zoned
Buying in Blue Bay? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 0.54 km², Blue Bay is relatively unconstrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. The dominant land-use zone is General Residential. The median lot measures about 697 m² across 446 parcels. These figures are suburb-wide - the overlays that actually apply to a given lot can differ block to block, which is what a property-level check tells you.

Is Blue Bay flood-prone?
We don't yet hold flood mapping covering Blue Bay, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Central Coast is the authority to check for flood mapping in this area. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.
Is Blue Bay bushfire-prone?
Bushfire mapping covers Blue Bay and little to none of it is mapped as bushfire-prone (the Central Coast average is 69%). Always confirm for the exact lot, as mapping can change.
What is the zoning in Blue Bay?
The dominant planning zone in Blue Bay is General Residential, though the suburb also includes Public Recreation and Low Density Residential. Zoning sets what you can build and do on a site, and can differ lot by lot.
Does Blue Bay have heritage-listed places?
No heritage-listed places are on record within Blue Bay. Even so, it is worth confirming for an individual property before any works.
What is the typical lot size in Blue Bay?
Across 446 surveyed parcels in Blue Bay, the median lot size is about 697 m². There are also 12 registered easements mapped in the suburb - an easement can restrict where you can build, so always check the title and overlays for the specific lot.
Does Blue Bay have a train station?
There is no train station inside Blue Bay itself. The suburb is served by 16 bus stops.
What is the population of Blue Bay?
At the 2021 Census Blue Bay had 1,060 usual residents, with a median age of 52 and an average household size of 2.1 people. The wider The Entrance statistical area, which contains Blue Bay, went from 11,941 people in 2001 to 16,336 in 2025, up 37%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Blue Bay alone.
Is Blue Bay an advantaged suburb?
On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Blue Bay scores 983 and sits in decile 5 of 10 nationally and decile 5 within New South Wales - decile 1 being the most disadvantaged tenth of Australian suburbs and decile 10 the least. The national average score is 1000. SEIFA summarises income, education, occupation and housing across the whole suburb, so it describes the area, not any particular household in it.
What is the median household income in Blue Bay?
Median household income in Blue Bay was $1,323 a week at the 2021 Census, against $1,735 for the typical suburb in Central Coast. Median rent was $380 a week and the median mortgage repayment $2,167 a month. These are 2021 Census figures and have not been indexed to today.
Do I need a planning report for a Blue Bay property?
A Blue Bay planning report pulls every overlay - zoning, flood, bushfire, heritage and environmental - that touches a single lot, on live council and state data. The interactive map preview is free; a full PDF report is $9.
