APPLE boss Tim Cook sent his well wishes to Australia in a congratulatory tweet following the vote on same sex marriage — there was just one slight problem.

The man responsible for making the most recognisable smartphones in the world apparently needs to work on his emoji game because he tweeted the wrong flag alongside the message.

As some eagle-eyed social media users pointed out, Mr Cook — who was accidentally outed as being gay by a CNBC host live on TV a few years ago — included the New Zealand flag in the tweet.

He did, however, correct his mistake by issuing a new tweet with the correct flag.

Congratulations Australia! Another important step toward equality for all. 🇦🇺 #MarriageEquality — Tim Cook (@tim_cook) November 15, 2017

Of course given the tiny size of the flag emoji and the even more subtle difference between our flag and that of our Kiwi counterparts, the Apple CEO could be forgiven for the mistake.

But a handful of Twitter user weren’t going to let him get away without a light ribbing.

Wrong flag Tim 😉🇦🇺 — Chris Wachtler (@Chris_Wachtler) November 15, 2017

Tim, thank you. You did use the New Zealand flag, but thanks. — Zac Davies (@ZacDavies) November 15, 2017

Fairly sure that’s the New Zealand flag 🇳🇿... they’ve had #marriagequality for ages now!

iPhones have this cool feature where if you type the country it suggests its flag to you. Who knew? — Josh Sanderson-Kirk (@JoshSK1) November 15, 2017

Wrong flag brother... it’s this one 🇦🇺 — Albert. 🏳️‍🌈 (@albs_bruh) November 15, 2017

If Tim Cook picking the wrong country flag for Australia isn't motivation enough for Apple to redesign the emoji picker, than I don't know what is https://t.co/dX9ifTeVfC — Pat Murray ❤️🧡💛💚💙💜 (@_patmurray) November 15, 2017

Thanks anyway Tim,
