Rugby-mad youngster Callum Harper has barely slept all week.
A fullback with the Wollongong Vikings under 13 team, Callum will run onto the field with the Wallabies when they take on the mighty All Blacks in tonight's Bledisloe Cup clash in Sydney.
He has been counting down the days to his chance-of-a-lifetime opportunity, which he was fortunate enough to win through an ARU-run competition.
"I can't wait," the Smith's Hill year 7 student said.
"It'll be awesome to be out in the middle of the field before the game, to see and hear the crowd and to be standing there for the national anthem.
"It will probably be an experience I'll never forget. I'm really looking forward to it," 13-year-old Callum said.
He will be allowed special access to the Wallabies' dressing room and warm-up area, seeing first-hand how they prepare for the biggest game of the Test calendar.
"Callum knows he's very lucky to receive such a wonderful opportunity and he's very excited about it," his father Andrew said.
Callum will be decked out in his full Vikings playing kit for the match.
His family will be at the game and they plan to make a video keepsake.
