McDonald’s is currently testing a new menu item in specific Australian locations.

McDonald’s has unveiled a clandestine addition to its menu after eagle-eyed fans spotted it – but it’s not available everywhere.

The fast-food behemoth is testing out Wavy Fries, a crinkle-cut chip that packs more thickness than the standard Aussie fries.

Although limited to specific outlets for now, the introduction of this new item, previously a hit in France, hasn’t dampened the enthusiasm of potato lovers.

“McDonald’s Australia is currently trialing Wavy Fries in select restaurants across New South Wales,” confirmed a spokesperson to news.com.au.

“We eagerly await our customers’ feedback and anticipate sharing more details in the near future.”
