Near T4 security, JB Hi-Fi is your last-minute tech stop
Right in Melbourne Airport’s T4 domestic area, JB Hi-Fi fills the gap for things you forgot to pack: cables, chargers, headphones, SD cards and basic phone accessories. Prices track their regular Australia-wide retail tags, not the heavy airport markups you see elsewhere, so you won’t feel punished for grabbing a $20–$40 cable on the way to your gate.
The store sits airside in Terminal 4, so it’s usable for Jetstar, Rex, and some Tigerair-legacy routes that still use T4 gates. Stock usually covers mainstream brands you’d see in a standard suburban JB: Apple and Samsung accessories, Logitech gear, and plenty of cheap backup options if you just need something that works for the next 3-hour flight.
Expect typical airport daytime hours that roughly match T4’s first and last wave of departures; think early-morning opening before 06:00 and closing in the late evening when the final domestic flights head out. If you land in T4 on a late-night arrival, don’t count on it still being open past about 21:00–22:00.
JB Hi-Fi in T4 mainly helps with break/fail moments: a dead pair of earbuds before a 5-hour MEL–PER hop, a missing HDMI cable for a client presentation, or a power adapter for a laptop with 10% battery. Expect carry-on friendly items more than big TVs or home audio setups; this is airport scale, not superstore scale.
Tip: if you’re eyeing anything over about $100, quickly check the JB Hi-Fi website on your phone; staff usually match their own online price on the spot if it differs.
