Faith Hill and Tim McGraw are getting ready to reprise their successful Soul 2 Soul tour in Australia next month, and the superstar couple couldn't be more excited about their upcoming trek.

"It will be my first time," Faith acknowledges to 'Good Morning America' host Robin Roberts. "Tim's performed there before. We're going to cross the ocean -- way across the ocean."

"It's like next year in Australia," Tim jokes.

The parents of three girls -- Gracie, Maggie and Audrey -- are eager to take their daughters with them Down Under.

"They're very excited about going," notes the 'Better Than I Used To Be' singer. "Last year we had a good time. We're there a little longer this time than we were last year. When [Faith] goes with me, they want to see more shows. When I'm by myself, there's only like two shows. When she goes with me, we sell more tickets so we have to do more shows."

The husband and wife, whose joint endeavors also include a Soul 2 Soul fragrance line, hint that they may be doing even more collaborating in the future. "I'm sure that we will [do an album together] at some point," Faith acknowledges. "We are together all the time, and we have great ideas about what we'd like to do."

Her self-deprecating husband jokes that his superstar spouse will have to make a big sacrifice to do an entire CD with him. "It's OK to lower her standards for a song or two, but for a whole record, I don't know if she wants to do that ... get down in the gutter for that long."

Tim will follow up his trip halfway around the world with a series of shows much closer to home, when he hits the road with his good friend, Kenny Chesney, for their Brothers of the Sun tour. And even though the 19-city trek will take her hubby away from home, Faith is fully supportive of the endeavor.

"It's going to be great," gushes the 'Come Home' singer. "They go way back. Tim has known Kenny 20-something years -- longer than we've known one another. He's a dear friend. It should be fun. It's not brain surgery. They should go out there and have a good time. The fans are very excited to see the show."

2012 will be a big year for country's reigning power couple. Tim's long-awaited album, 'Emotional Traffic' debuted at No. 1 last month. His songbird wife is also wrapping up a new set of tunes, which will be her first studio album in more than six years.
