how much does a timing belt cost to replace

Short answer: in Australia, a timing belt replacement generally runs about $600–$1,000 for simple 4-cyl engines, $900–$1,600 for many family cars, and $1,200–$2,500+ for V6/V8 or tight engine bays.

That usually includes a belt kit; smart money also replaces the water pump, tensioners, and seals, adding roughly $200–$600.

Expect the higher end at dealers, the lower end at independents, and extra if your engine is a boxer, turbo, or stuffed into the bay like a deckchair in a carry-on.

Get itemised quotes, ask for genuine or quality aftermarket parts, and do it on time—snapped belts can turn your engine into modern art, very expensive modern art.
