Murray had been expected to fly to Melbourne this week to quarantine for two weeks ahead of the first Grand Slam of the year but that was put on hold after the positive result, which came to light this morning.
He is currently isolating at his Surrey home but the three-time Grand Slam champion is still hopeful he can recover from Covid in time to travel to Australia for the event, which gets under way on February 8.
Murray last played at the Australian Open at the start of 2019 after which he underwent hip surgery but he has played just two Grand Slam tournaments since then, losing in the first round of last year’s French Open and suffering a defeat in his second-round match at the subsequent US Open.
Despite the positive coronavirus test, Murray is believed to be in good health and confident of playing at a high level at a tournament in which he is a five-time runner-up.
His provisional plans are to travel at a later date but only to do so when it is completely safe and the appropriate permission is granted from the authorities.
Murray’s camp is believed to already be in discussions with Australian Open boss Craig Tiley about his participation in the event and his potential late arrival.
Health officials in Melbourne have previously made it clear that no player can travel to Australia without a negative test.
But dispensation was made for American Tennys Sandgren, who originally contracted Covid back in November but still produced a positive test on Monday. Following lengthy negotiations with officials Down Under, he was given the all clear to fly from the United States late last night.
