Parents swarmed the retailer’s social media to complain of queues, customers hoarding stock and items selling out.
The suits, which usually retail at $24.95, were selling at the bargain price of $11.99.
The range is notorious for its sell-on value with some suits selling for hundreds in secondary markets. One Strawberry ‘Zippy Wondersuit’ sold on eBay for more than $200 after 36 bids on Wednesday night.
The sale began when Aldi's doors opened on Wednesday morning, but many parents complained the suits had sold out only hours later.
"I went to four Aldi stores today (in four different towns) only to find that they had all sold out of Bonds Zippy suits before 9am," one user said.
"Very disappointed with my shopping experience at Aldi Minto today. Not only did they not have a single Bonds suit available when the special buys only started today, but your stock was mislabeled," another user said.

One parent said she arrived early but was too afraid to return to her car in case it cost her spot.
"I didn't want to lose my place in line so I stood with my baby in the freezing cold for 45 minutes and waited. As time went on more people arrived also expecting the 8am opening," she said.
Other users complained they were left empty-handed after some shoppers began hoarding stock.
"Would like to recommend that future sales of items like Bonds Wondersuits have quantity limits imposed, as all three stores in my local area sold out within an hour due to a very small amount of people buying trolley fulls [sic]," one user said.

"So I walked into Aldi at Fairfield West at 9:15am to get some Bonds Zippys which just went on sale today and to my surprise there were none left as one lady had filled her trolley with all of them," another user said.
"[It's] not uncommon to see customers queuing before opening hours in anticipation of the Special Buys being released that day," a spokesperson for Bonds Australia told The Daily Mail.
"We recommend visiting Aldi as early as possible when new Special Buys go on sale, as these products are available only while stocks last."
