Kurt Aylett and Anthony Miles from southern New South Wales and Shaun Edwards from the club's Northern Territory zone will join Sam Schulz, Mark Whiley, Curtly Hampton and rugby league convert Israel Folau on the Team GWS playing list from next year.
"Here we have another three very impressive young footballers joining this club from the outset," coach Kevin Sheedy said.
"These players are recognising the power of the opportunity that we are offering. We are going to be able to provide them the best development and welfare available as they embark on a career playing AFL football.
"Both Aylett and Miles had the opportunity to enter the draft this year but have elected to be a part of this club from the start - that's a pretty powerful message.
"Once again these boys are coming directly out of our zone. Believe me we are serious about our commitment to working with these areas. This is about finding the best talent we can and providing genuine opportunities to these young men.
"I have to tell you, I cannot wait to start working with these players."
Aylett, who grew up in Leeton, plays with the North Ballarat Rebels in the TAC Cup after moving south to attend boarding school in 2009.
An athletic midfielder with an excellent endurance base, Aylett has been a part of the AFL NSW/ACT Talented Player Program since he was 13, playing for the state at both under-16 and under-18 level.
Miles, an inside midfielder from Howlong near Albury, is hailed as a natural leader, having captained both the under-16 and under-18 NSW/ACT Rams at the NAB AFL Championships.
Miles is playing with the Murray Bushrangers in the TAC Cup for his second year after being runner up in the club’s best and fairest in 2009 as a bottom-age player.
Edwards is a 16-year-old from Darwin who will join NT Thunder teammate Hampton, who signed with the club last week.
Edwards played his junior football with St Mary's, where he won the NTFL's Lew Fatt under-13 medal before representing the Thunder at both under-16 and under-18 level.
