The Australian maverick enjoyed a successful year in 2022 and Murray thinks he can win his maiden Grand Slam on home soil.
Murray said of Kyrgios: "Last year he won the doubles here and then he had a great run at Wimbledon as well. He was really close and wasn't that far away at the US Open either.
"He's been knocking at the door over the past couple of Slams and hopefully he has a good preparation and everything to give himself the best chance.
"He can do it but it's not going to be easy."
Meanwhile, Murray insists he has no "timeframe" on his tennis retirement as he embarks on another year on tour.
The 35-year-old sports star said: "I still love hitting tennis balls, I'm fortunate I'm able to do it at a high level, it's not the level that it was five or six years ago but... I love the sport.
"I've been healthy the last seven months. I'm not awakening with aches and pains like in the last few years.
"As long as the body holds up well and I'm training properly and performing to a level I'm enjoying, then I will keep going. But I don't have a timeframe (for retirement)."
