The Scot was knighted in Britain's New Year Honours list after a magnificent 2016 and tennis chiefs have been mulling what to call him, according to the Sydney Morning Herald.
It said Channel Seven had decided to reference the three-time Grand Slam champion by his new official title when he plays his first match in Australia since being recognised by the Queen.
"Not only is he tennis royalty, he's now a Knight Bachelor, so yes of course we will be showing him the respect he deserves and refer to him as Sir Andy Murray," the broadcaster's head of sport Saul Shtein said.
"If he is walking out on to court and the announcer is calling him as Sir Andy Murray, that would be a bit weird, yeah," he told the Herald.
