The Nickelback frontman popped the question to the singer in August (12) after a whirlwind romance, but they faced separation just months later as Kroeger's group was booked to tour Australia.
Lavigne decided to jet Down Under and travel around the country with the band so the couple wouldn't have to spend any time apart.
She tells News.com.au, "I was actually just there (in Australia) with Nickelback on tour a few months ago. I didn't have to play so I got to enjoy the (cities). It was the first time I was there and not working... I was just kind of cruising... Travelling, going from hotel to hotel, airport to airport, venue to venue... It was exactly like being on tour and the hardest part of being on tour is travelling."
Lavigne admits another reason she decided to go away with Nickelback was so she could finally see her new partner perform live. She adds, "I hadn't really seen very many of his concerts because we only started dating in the summer."
