Australia is experiencing a growing shortage of canned sardines, with supermarket shelves being stripped bare as demand surges across the country.

Social media trends, particularly on TikTok, have turned sardines into a popular “superfood”, while rising living costs have also pushed more shoppers toward the affordable source of protein.

The sudden spike in demand has caused prices to increase almost overnight, leaving many consumers struggling to find their preferred brands.

Retailers are facing supply pressure as imported stocks fail to keep pace with the unexpected buying frenzy.

Nutrition experts say sardines remain an excellent source of protein, omega-3 fatty acids, vitamin D and calcium, but they advise Australians to maintain a balanced diet rather than relying on a single trending food.
