Where "Cobber" Comes From
"Cobber" means a close friend or mate, and is first recorded in Australian English in 1888, in the Sportsman (Melbourne). The word's origin is debated: the most widely discussed theory connects it to the Yiddish word "khaver" (friend or comrade), which traces back to the Hebrew แธฅฤแธฤr, and which may have entered London East End slang via the Jewish community there before travelling to Australia with British migrants. An alternative proposes the Suffolk dialect "cob" โ meaning to take a liking to someone.
"Cobber" became a badge of Australian national identity during the First World War, where it was the word Diggers used for their comrades in the trenches. It remained in widespread use through the 1920s, 30s, and 40s, before gradually falling from everyday currency in the second half of the 20th century. Today "cobber" is considered somewhat dated โ more likely to appear in a period novel or in affectionate invocations of old Australiana than in ordinary speech.

How Aussies Actually Use It
Largely nostalgic now โ "he's me old cobber from school" has a warm, old-fashioned ring, more likely from an older speaker or used for deliberate old-school charm.
Younger Australians reach for "mate" instead in daily life, but "cobber" still carries genuine affection whenever it's used.
