The much talked about trade was a little while in coming but was completed on Tuesday morning, with the Bulldogs acquiescing to the Swans' demand for a third-round draft pick.
A clearly relieved Hall said he had feared the negotiations would stretch throughout the week.
"It was a tense couple of days. I thought it would get done with a couple of minutes to go on Friday", he said.
"The uncertainty is gone and we can look forward to setting up down here and cracking into training.
"The hard work starts now."
Sydney Swans Senior Coach Paul Roos said Hall will be remembered fondly for his outstanding contribution to the Club.
“We were pleased to work with Barry and his manager Phil Mullen to accommodate his wish to get to the Bulldogs,” Roos said.
“As has been said before, Hally will always be remembered as a fantastic player, a premiership player, and no-one will forget him raising the cup after the premiership win in 2005. We wish him all the best in his new role at the Western Bulldogs and hope he is as successful there as he has been at the Swans.”
