Amazon’s Big Smile Sale this week has so far been a great source for bargain hunters, including lots of tech as evidenced by our continued live coverage of the shopping event. Ranging from big-ticket items like the iPhone 17 to cheap tech upgrades under AU$50, there are plenty of deals to score if you know where to look.

I’ve recently had a stab at some home upgrades over the past year, and while the likes of Ikea and Bunnings were great for big-ticket items, I’ve found Amazon to be a fantastic source as well, particularly when looking for kitchen and bathroom tech.

Browsing through the Amazon Big Smile Sale has pointed me to plenty of home upgrades, including many that cost less than AU$100.

From WFH setup upgrades like mice and audio gear, to home-security systems and even self-care investments like hair dryers and trimmers, I’ve found some great Amazon picks for under AU$100 below. I’ve even included affordable audio gear and a dash cam that we’re particularly fond of here at TechRadar, as well as tech essentials like portable and wireless chargers.
