Alternator Replacement Cost by Brand (Australia)

Alternator cost is driven mostly by the part — European alternators carry a 40-60% parts premium over Japanese equivalents, and some require coding to the vehicle after fitting. Labour is typically 1-2.5 hours across all brands.

Rebuilt vs new:a rebuilt alternator ($150-$300 less) usually carries a 12-24 month warranty and is fine for older cars; new is worth it on late-model start-stop vehicles that need higher-output AGM-compatible units. Second-hand wreckers' units often carry only a 30-day warranty — the saving rarely justifies it. If the battery warning light comes on with a whining noise, test the battery first — a $150 battery can mimic a $700 alternator fault.
