Jack, who was joined by GWS forward Dylan Addison, climbed the Sydney landmark with the NSW under-12 team, who will compete in the National AFL School Championships, to be held in Sydney this week.
A former Pennant Hills junior and NSW representative player, Jack said he enjoyed sharing his experiences with the best young AFL talent the state has to offer.
“What an opportunity for them to climb the Bridge and they’ve also got the carnival this week, so it’s an exciting week for them,” Jack said.
“For me and Dylan, the schools carnival was where our journeys began, so to see these kids and have a chat to them and hopefully inspire them was terrific and is hopefully something they’ll never forget.
“It was fantastic to encourage these boys to keep training hard and to wish them a little luck on their own journey.”
Both Jack and Addison represented NSW in the under-12s at the National AFL School Championships in 1998.
While the development of AFL talent in NSW was very much in its infancy when Jack and Addison were coming through the ranks, Jack said it was clear that local players now had a greater understanding of the game.
“What we found was that they love their football,” Jack said about his experience with the under-12 team.
“They are also quite knowledgeable about AFL football, which I don’t think ten years ago the kids would have been.”
Jack said he was thrilled to see so much local interest in the game and said he felt both the QBE Sydney Swans Academy and the GWS Academy had played important roles in developing the game in NSW.
“Certainly the NSW boys that we spoke to were really enjoying it and were enjoying it at the grassroots level,” he said.
“All of their friends are starting to play, which I think is a result of the Academy system being set up, so hopefully that can continue.”
