The actress turned to Instagram to share a sweet video of herself lovingly watching Urban on a laptop computer from Australia.
"Wishing I was there, but streaming @KeithUrban on the #ACMawards here in #ByronBay 💖 #Nashville," Kidman wrote alongside the clip.
Urban, who went into the night as the reigning ACM Entertainer of the Year, hosted the awards from the Grand Ole Opry House in Nashville. The three-hour ceremony also broadcasted live from Nashville's famed Ryman Auditorium and The Bluebird Cafe.
In addition to hosting, Urban also hit the stage for the debut performance of his new collaboration with P!nk, "One Too Many." The performance marked the world premiere of the song, which is featured on Urban's upcoming new album, The Speed Of Now Part 1, which is due out on Friday (September 18).
Additional performers for the night included Taylor Swift, Blake Shelton featuring Gwen Stefani, Carrie Underwood, Trisha Yearwood, Kane Brown, Luke Bryan, Eric Church, Dan + Shay, Florida Georgia Line, Mickey Guyton and Morgan Wallen, who performed at the Opry. Gabby Barrett, Riley Green, Old Dominion and Thomas Rhett featuring Jon Pardi, performed from the Ryman alongside Ballerini. Jimmie Allen, Luke Combs, Miranda Lambert featuring songwriters Natalie Hemby and Luke Dick and Tim McGraw took the stage at The Bluebird.
