Median house price
No open median house price for The Gap (Mount Isa - Qld).
Queensland sells its property sales records through licensed brokers rather than publishing them openly, so there is no official suburb median we can show. ABS median established-house price, Greater Brisbane: $1.1M; Rest of Qld: $815k.

Percentiles rank this suburb against Queensland suburbs that carry the metric — never across states, and never against suburbs where it is missing. Price references are ABS median established-house transfer prices for the Mar 2026 quarter (CC BY 4.0); the suburb figure is a Valuer-General median over a different window, so read the gap as indicative. Income references are the Census 2021 median of the middle suburb in Queensland and nationally, not a household-weighted median.

Shares are the proportion of the suburb's land area. Land where Landsat saw water in at least 1% of clear passes since 1987, excluding permanent water and filtered by DEA's confidence layer. Satellites miss flood peaks, so this is a floor, not a risk estimate; dense high-rise cores can still register tower shadow as water. Designated for development control; a designation, not a prediction of fire behaviour. Includes the potential-impact buffer around bushfire prone vegetation. Mapping vintages differ by region (South East Queensland 2017, elsewhere 2014). Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled. No open statutory flood layer is published for Queensland yet.
Planning & zoning
Listed heritage places
0
State-listed only (Qld Heritage Register)
Zones are grouped into ten families so states compare; the council's own scheme is the authority for any one lot. Listed-place counts follow each state's own list, so they do not compare across states. Queensland has no statewide zoning map — each council publishes its own. Source: Queensland Heritage Register.
