The performance struck a chord with homesick New Zealanders who commented on the post to let them know how much it meant to them to listen to the song.
"Brings tears to my eyes having sung it a few times in the past whilst travelling," one person commented.
"Ahhh so there is someone cutting onions, thought it was just me with a tear or two #MissHome," another person said.
"That was awesome. I've lived in Oz for 43 years and this song always makes me feel homesick for NZ, beautifully sung,' another Twitter user added.
New Zealand and Australia formed a transtasman bubble that officially kicked off on Monday, leading to emotional reunions at international arrival halls of airports in both countries.
