Short answer: there was no 2023 Subaru WRX STI sold new in Australia—Subaru parked the badge for this generation.
New price: not applicable in 2023.
Used price: expect roughly AUD 40,000–80,000+ for 2015–2021 STIs in good nick, with low‑km or limited editions asking more and higher‑km cars sitting lower.
Hunt the classifieds (Tradingpost, dealer sites) and budget for a thorough inspection—bonus points if the clutch isn’t made of confetti.
