Short answer: there’s no single “cheapest” site for every item, but the lowest-priced fashion in Australia is usually found on ultra‑low‑cost marketplaces such as Temu and Shein; among Australian retailers, Kmart, Big W, Target and Best & Less are the cheapest for many basics. (findershopping.com.au)

Quick comparison (pros / cons)

• Temu — often the lowest sticker prices and free standard shipping on many items; best for ultra‑cheap bargains but variable quality, safety and supply‑chain transparency. (findershopping.com.au)
• Shein — very low prices on trend pieces (many items under AU$15), big selection; quality and ethical concerns are commonly reported. (au.shein.com)
• Kmart / Big W / Target / Best & Less — inexpensive Aussie retailers with low prices, fast local delivery/returns and generally more reliable safety/consumer protections than some offshore marketplaces. Good value for basics and “dupes.” (couriermail.com.au)
• Marketplaces (eBay, Amazon, Catch) — can be very cheap depending on seller and sales; good for deals and clearance stock but price varies by listing. (findershopping.com.au)

What to watch for

• Compare total cost (item price + shipping + return costs + possible import duties). Temu/Shein can look cheapest on the ticket price but extra charges, long returns or safety issues can change the value. (findershopping.com.au)
• Check reviews, sizing info and product photos; very cheap items often have inconsistent quality. (au.shein.com)
