Miami
Housing stock splits into almost perfect thirds: 31.5% houses, 36.7% apartments, and 31.6% semi-detached, an unusually balanced mix for the Gold Coast. Vacancy at 15% is among the highest in the region, yet population growth of 1.34% per year (114 persons annually) signals sustained demand. The median age of 37 sits 3 years below the national average, and the gentrification score of 25 with early signs suggests the demographic composition is shifting. Population expanded 16.9% over 10 years, accelerating from 8% to 19% growth, a pace that has outrun infrastructure.

Estimated from rent (2025)
The estimated median of $578,000 positions Miami below the Gold Coast's beachside premium suburbs like Burleigh Heads or Palm Beach. Two-bedroom homes dominate at 41.1%, reflecting the apartment and townhouse majority. Mortgage stress at 25.2% of income sits below the 30% threshold, and weekly mortgage repayments of $2,000 are manageable against household income of $1,831/week. The 33.6% couples-without-children rate and average household size of 2.2 (0.3 below national) suggest buyers are typically couples or downsizers rather than families seeking larger homes.

The estimated median of $578,000 positions Miami below the Gold Coast's beachside premium suburbs like Burleigh Heads or Palm Beach.

Mortgage stress at 25.2% of income sits below the 30% threshold, and weekly mortgage repayments of $2,000 are manageable against household income of $1,831/week.

For Investors
Renters account for 40.5% of residents, above the national average, providing a solid tenant base. Weekly rent of $470 against a $578,000 estimated median delivers competitive gross yield. However, the 15% vacancy rate is a serious concern, well above Gold Coast averages and indicative of seasonal or oversupply dynamics. Zero development applications in 12 months may eventually help absorb excess stock. Net overseas migration of 159 per year is the primary growth driver, and internal migration adds 29, suggesting both channels feed tenant demand.

Demographics
English ancestry dominates at 3,166, followed by Irish (1,007) and Scottish (831), with 23.9% born overseas, 2.3 points above the national rate. Portuguese (99 speakers) is the top non-English language, an uncommon pattern on the Gold Coast, followed by German (19), French (14), Italian (13), and Japanese (12). University attainment at 36.1% sits 6 points above the national average. The 33.6% couples-without-children share and 2.2 average household size indicate a suburb oriented toward professionals, retirees, and lifestyle migrants rather than large families.

The balanced stock of 31.5% houses, 36.7% apartments, and 31.6% semi-detached makes Miami one of the Gold Coast's most diversified housing markets. Two-bedroom dwellings dominate at 41.1%, while 4-plus bedrooms account for just 15.6%. Ownership splits 25.7% outright, 33.8% mortgage, 40.5% renting. The high renter share combined with low outright ownership (compared to 30%+ nationally) suggests a transient population. Rent-to-income at 25.7% keeps tenants below stress levels, though mortgage-to-income at 25.2% is also comfortable relative to Gold Coast norms.

Frequently Asked Questions
Is Miami a good suburb to live in?
Miami offers beachside living with a $578,000 estimated median, well below Gold Coast premium like Burleigh. The SEIFA IRSAD decile of 7 places it above the national midpoint. Walking and cycling at 6.2% is higher than most Gold Coast suburbs. The 15% vacancy rate suggests a looser rental market, which can mean more housing choice for buyers.
What is the median house price in Miami?
The estimated median is $578,000, derived from 2025 rent data. Two-bedroom homes dominate at 41.1% of stock, reflecting the apartment and townhouse majority. The housing mix is unusually balanced: 31.5% houses, 36.7% apartments, 31.6% semi-detached.
What schools are in Miami?
Miami State High School is the suburb's sole school, a government secondary with an ICSEA score of 1032 and 1,542 enrolments. The ICSEA sits 32 points above the national benchmark of 1,000. No primary schools are located within the suburb boundary.
Is Miami safe?
Suburb-level crime data is not available for Miami in the current dataset. The SEIFA disadvantage decile of 7 places it above the national midpoint, which typically correlates with moderate crime levels. QLD Police report crime statistics at the broader division level.
Is Miami good for property investment?
The 40.5% renter rate and $470 weekly rent provide strong yield potential against the $578,000 median. However, 15% vacancy is a major risk factor, well above Gold Coast averages. Zero DAs in 12 months mean no immediate supply additions. Population growth of 1.34% annually, driven by overseas migration of 159 per year, sustains medium-term demand.
How is Miami's population changing?
Population grows at 1.34% per year, adding 114 people annually. Growth over 10 years reached 16.9%, accelerating from 8% to 19%. Net overseas migration of 159 per year is the primary driver. Medium projections forecast 8,935 by 2031, up from 8,531 in 2025.
How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
