The dick-swinging contest between Melbourne and Sydney continues to escalate, with the latest battleground being Sydney Airport's radar failure.
"Who woulda thunk it? Sunny Sydney's radar fails! Come to misty Melbourne (lol) when you can folks!" Tweeted the official City of Melbourne Twitter handle.
The City of Sydney, never one to back down, returned fire with: "One day in spring mate. How's the ghost town goin' on NYE or Australia Day."
That was followed up with: "Do you even celebrate Australia Day down there anymore?"
With both cities aiming to pave a 100km radius from their city centres and have the most expensive house prices in the world, this battles looks set to continue.
