Looks like Tim Cook might have sent this tweet out a little too quickly.

The Apple CEO on Wednesday congratulated Australia on saying "yes" to same-sex marriage -- except he added an emoji of the flag of New Zealand.

The original tweet was quickly deleted and a new tweet sent out, this time, with the correct flag.

But the mistake had already been spotted by some on Twitter, and one guy pointed out how it's tough searching for emoji on Apple's keyboard:

To be fair, the Australian and New Zealand flag do look pretty similar.

Both have Union Jacks on them, except the Australian flag features the Commonwealth Star. The stars are also of different colours.

Apple had earlier this year weighed in on Australia's same-sex marriage debate, saying that it supported "marriage equality and believe all Australians deserve the freedom to marry the person they love."

Apple has long been a supporter of marriage equality. In 2016, its logo joined the Australian Marriage Equality page, alongside other major companies like Google, Microsoft, Twitter and IBM.

Cook, who came out as gay in 2014, has lead the company's pro-equality message.

The then 53-year-old, who's famously private, said it was "worth the trade-off" of his privacy if it helps someone else.

"If hearing that the CEO of Apple is gay can help someone struggling to come to terms with who he or she is, or bring comfort to anyone who feels alone, or inspire people to insist on their equality, then it’s worth the trade-off with my own privacy," he said.
