Forget the underarm bowling incident of 1981, forget the trans-Tasman rugby rivalry, Kiwis and Aussies are officially BFFs.
That's according to Australian participants in a newly released Lowy Institute poll, which saw Aussies rate their antipodean sibling as their global "best friend", toppling the United States from their previously held position.
The upset is evocative of 2015's viral "friendship ended" meme, where Pakistani man Asif Rasa Rana turfed his best-friend Mudasir, declaring their friendship ended and that his new best friend was Salman.
His poorly photoshopped declaration was all too applicable to the newly released poll result.
The Lowy Institute, a Sydney think tank, released its annual poll testing Australians' attitudes to international and domestic issues.
Key findings showed most Australians were worried about where the world was headed, but were more confident about their country's future, with about half saying they were satisfied with the state of the nation.
However the most striking finding for us Kiwis was New Zealand's ascension to "best friend" status, overtaking the United States as the preferred answer when Australians were asked who their "best friend" in the world was.
New Zealand comes first, with 53 per cent (up 21 points since 2014) nominating it as Australia's best friend, beating the United States, the United Kingdom, China, Japan, and Indonesia.
Once named as Australian's closest buddy, the US now has to contend with sharing the lowly status of second-best friend with the United Kingdom.
