"Hard Yakka" is Australian slang that means "hard work," particularly manual labor. The word "yakka" itself originates from the Yagara language, an Indigenous Australian language, where it meant "work". The term gained prominence in the 1840s and is commonly used in Australia to describe strenuous or demanding work. The name "Hard Yakka" was adopted by a workwear company to promote its Australian heritage and rugged products.
