How Rockville is zoned
Selling in Rockville? The lot-level zone is the zoning Part 3 of Queensland's Form 2 seller disclosure statement asks for - see our Form 2 planning data guide.
Across its 1.94 km², Rockville is relatively unconstrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay. The dominant land-use zone is Low Density Residential. The terrain is gently undulating, and the median lot measures about 652 m² across 1,534 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.

Where can I see a flood map of Rockville?
The schematic on this page is a Rockville flood map: the mapped flood overlays drawn over the suburb's terrain and street grid. Flood lines vary block to block, so for a specific property use the free interactive map - search any Rockville address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.
Is Rockville flood-prone?
Flood mapping covers Rockville and none of the suburb falls within a mapped flood overlay (the Toowoomba Regional average is 13%). Looking lot by lot, 0% of the 1,648 properties we analysed in Rockville carry some level of mapped flood risk, including 1 rated high risk or historically affected. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.
Is Rockville bushfire-prone?
Bushfire mapping covers Rockville and little to none of it is mapped as bushfire-prone (the Toowoomba Regional average is 20%). Always confirm for the exact lot, as mapping can change.
What is the zoning in Rockville?
The dominant planning zone in Rockville is Low Density Residential, though the suburb also includes Low-Medium Density Residential and Low Impact Industry. Zoning sets what you can build and do on a site, and can differ lot by lot.
Does Rockville have heritage-listed places?
No heritage-listed places are on record within Rockville. Even so, it is worth confirming for an individual property before any works.
Is Rockville hilly or flat?
Rockville is gently undulating: the median lot slope is about 4%, and 1% of properties sit on slopes of 15% or steeper. Ground level runs from roughly 588 m to 637 m AHD across the suburb. Slope drives site costs - cut and fill, retaining walls and driveway grades - so it is worth knowing before you commit to a sloping block.
What is the typical lot size in Rockville?
Across 1,534 surveyed parcels in Rockville, the median lot size is about 652 m². There are also 68 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 Rockville have a train station?
There is no train station inside Rockville itself. The suburb is served by 13 bus stops.
What is the population of Rockville?
At the 2021 Census Rockville had 3,204 usual residents, with a median age of 38 and an average household size of 2.3 people. The wider Wilsonton statistical area, which contains Rockville, went from 12,691 people in 2001 to 14,669 in 2025, up 16%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Rockville alone.
Is Rockville an advantaged suburb?
