Looking for a song version from Country 105

We lived 80km out of town, but my Mama always had Country 105 blasting every Saturday and Sunday morning. During the holiday season, they'd have a version of "Gramma Got Run Over By A Reindeer" sung by Aussies or NZ. Song version wouldve been played during the 90s and early 2000s, if not earlier. It's not Irish Rovers or Dr Elmo (wrong accents). Mama can't remember the group. Any help is MUCH appreciated.
