Baby stuff from KMart, Target... baby snacks from Coles.. take your pick. I got my Tula online from Australia. Forgot which online shop already, but it seems cheaper there.
Try Chemist Warehouse too https://www.chemistwarehouse.com.au/buy/81542/baby-u-baby-wipes-fragrance-free-240-pack. They have branches across Australia. But I never really got diapers/wet wipes from there. I only bought baby milk powder from them. It’s cheaper than Fairprice here 😅
