The aftermarket's quiet advantage: Australians are keeping their cars
Cost-of-living pressure and high new-vehicle prices are extending fleet age. Fitment data decides who benefits from it.
While the new-vehicle market has spent 2026 absorbed in EV share and emissions penalties, something quietly favourable has been happening in the aftermarket. Australians are holding onto vehicles longer — pushed by cost-of-living pressure and high new-vehicle prices — and an ageing fleet means more servicing, more replacement parts and more accessories.
The forecasts reflect it. The Australian automotive aftermarket is projected to grow at around 5.3 per cent annually through 2033, and the accessories segment specifically at close to 6.8 per cent CAGR toward 2034.
Growth in this category is not, on the whole, a demand generation problem. It is a discoverability problem.
Fitment is the entire funnel
An aftermarket buyer almost never asks “what accessories exist”. They ask “does this fit my 2019 Ranger”. If the answer is not available in seconds, with certainty, they leave — and they leave for whoever answers it fastest, not whoever has the better product.
Which means the fitment data layer is the single largest revenue lever most parts and accessory businesses have, and it is usually treated as an IT or operations issue rather than a marketing one. In practice it shows up everywhere marketing gets measured:
- Site search returns nothing useful for a vehicle-specific query.
- Shopping feeds get disapproved, or serve the wrong variant, because the vehicle attributes are incomplete.
- Paid search spends on high-intent fitment queries that land on a page that cannot confirm fitment.
- Returns climb, because the buyer guessed — and returns in this category are expensive and destroy margin quietly.
Spending media on a catalogue with weak fitment data is paying to expose a problem rather than paying to fix it. The order of operations matters: get the data right, then scale the spend.
Where the accessory growth actually is
The above-average growth is not evenly spread. Consumer electronics and convenience categories are running hardest — infotainment and navigation, dash cameras, parking assistance, LED lighting upgrades and smart device integration — driven by buyers expecting an older vehicle to behave like a modern one.
That is a useful signal for two reasons. First, it is a retrofit market by definition, and it grows as the fleet ages. Second, it is a technology purchase, which means the buyer researches comparatively and rewards clear technical content in a way that a purely mechanical part does not.
The 4WD, touring and ute modification categories remain the cultural core of the Australian aftermarket, and they are the least forgiving of loose marketing. This audience knows the ratings, the tolerances and which competitor cuts corners. Overclaim a load rating or gloss over an ADR implication and the correction will be public, detailed and permanent.
The electric shift is arriving quietly
Electrification is reshaping this category more slowly than the new-vehicle market, and that is being widely mistaken for it not happening.
Servicing patterns change: fewer fluid and consumable items, more diagnostic and software work, different wear profiles. Some traditional revenue lines shrink. But new categories appear at the same time — charging accessories, protection, thermal management, vehicle-to-load equipment, EV-specific touring and towing solutions — and very few Australian brands have moved on them properly.
With BEVs now above 20 per cent of new-vehicle sales, those vehicles are entering the aftermarket-relevant part of their life within a few years. The brands that build category authority now will be the default when that fleet arrives. The ones that wait until the volume is obvious will be buying their way into a category somebody else already owns.
The channel problem
Most businesses here sell through several channels at once — direct, retail, installer and workshop — and each wants something different. Direct-to-consumer activity that undercuts the network creates problems that outlast the campaign that caused them.
It is manageable, but it needs to be designed rather than negotiated after the complaints start: distinct messaging per channel, pricing discipline agreed in advance, and separate programmes for trade audiences. Trade marketing in this category is chronically underdone, which also makes it one of the cheaper places to gain ground.
