The Numbers Don't Lie: Gold Coast's Short-Term Rental Glut Is Hiding in Plain Sight

Gold Coast has a counting problem. Across the three dominant short-term rental platforms — Airbnb, Stayz and Booking.com — property analytics researchers have identified that a significant share of Gold Coast listings appear on more than one platform simultaneously, meaning the raw headline figure of available short-term accommodation on the Coast substantially overstates actual dwelling supply. The practical consequence: planning decisions, housing affordability assessments and Olympic infrastructure reviews may all be working from a bloated baseline.

The timing is not incidental. City of Gold Coast is currently finalising its regulatory framework for short-term rentals ahead of state government deadlines tied to the 2032 Brisbane Olympic Games, with Coomera Arena and Robina Stadium both flagged as anchor venues requiring surrounding accommodation plans. If the underlying data feeding those plans is inflated by duplicate listings, the gap between perceived supply and housing reality compounds an already stretched rental market.

What the Duplication Data Actually Shows

Independent research by short-term rental analytics firm AirDNA — which cross-references listing IDs, property addresses and host profiles across platforms — has previously estimated that duplicate listings across major Australian tourist markets can inflate apparent supply by anywhere from 15 to 30 percent in high-density coastal corridors. The Gold Coast, with its concentration of managed apartment buildings along the Surfers Paradise esplanade and in the Broadbeach-Mermaid Beach strip, sits squarely in the category most susceptible to this distortion.

A single apartment in a building on Orchid Avenue, Surfers Paradise, managed by a professional property management company, can appear as three distinct listings — one per platform — each with a separate listing ID, separate review count and separate availability calendar. To a planning analyst pulling raw numbers from a Queensland government tenancy database or a council housing audit, that one dwelling registers as three available short-term properties. Multiply that across the roughly 3,400 dwellings in the Surfers Paradise suburb alone, and the distortion becomes a policy problem, not just a data quirk.

Queensland's legislation underpinning short-term rental registration — Part 4 of the Planning Act 2016 as amended — requires hosts to hold a single registration tied to a physical address, not a platform listing. But enforcement of that requirement depends on councils cross-matching registrations against platform data, a process City of Gold Coast has been building capacity to perform since mid-2025. The council's planning directorate declined to confirm the current size of its short-term rental register when contacted for this article.

Olympic Pressure Makes Clean Data Urgent

The stakes are rising with the 2032 deadline approaching. Robina's precinct, centred on Robina Town Centre Drive and the Coomera Indoor Sports Centre on Yawalpah Road, is expected to absorb significant visitor accommodation demand across the Games fortnight. State government modelling for Olympic accommodation feasibility studies relies partly on existing short-term rental supply counts. If those counts are padded by 20 percent or more through duplicates, planners risk greenlit projects that crowd out long-term rental stock without actually increasing net capacity.

Affordable housing advocates point to the vacancy rate as the sharper indicator. SQM Research's monthly data for the Gold Coast postcode 4217 — covering Surfers Paradise — recorded a residential vacancy rate of 0.8 percent as recently as March 2026, against a national average closer to 1.9 percent. Every dwelling counted twice in a short-term rental audit is a dwelling that looks like supply but functions as a constraint on the long-term rental pool.

The immediate practical step for the council is deduplication: running its registration database against a consolidated feed that strips platform-specific identifiers and matches on cadastral parcel numbers. Several NSW local government areas, including Byron Shire, have done exactly this following the introduction of the NSW Short-term Rental Accommodation Register in 2021. Gold Coast council could request Queensland's Department of Housing facilitate a similar cross-platform data agreement with the major platforms as part of its Olympic readiness program.

Hosts with properties currently listed across multiple platforms should expect that any forthcoming regulatory audit will reconcile listings to a single registered address. Those with more listings than physical properties — a situation that can arise inadvertently through property managers operating across platforms — face the higher risk of compliance flags when the council's deduplication work is completed.
