Over 100 junior footballers participated in tackling drills and a game of touch with 'GI' as well as one of the Alexandria Rovers' Coaches Anthony Mundine.
The Rabbitohs players, through Souths Cares, were in attendance for over an hour and a half and handed out hundreds of posters and caps to those players who worked hard in drills.
Alexandria Rovers Club President Perry Johnstone said it gave the kids a huge thrill and has inspired them for a massive year.
"On behalf of everyone at the Alexandria Rovers JRLFC can I say a big thank you to Greg Inglis, Matt King and yourself (Souths Cares General Manager Shannon Donato) for attending training last night," Mr Johnstone wrote in a thank you letter to Souths Cares.
"As you witnessed first-hand last night the kids were buzzing having you guys there, plus the parents were happy to see you all there as they all wanted to get in on the show.
"To have both players stay there longer and sign every autograph and take all the pictures longer than the alloted time speaks volumes to both men."
