Jai Serong is traded to Sydney, with the Swans sending a future third to Hawthorn for the defender and a future fourth.
"We look forward to Jai arriving at our club and getting stuck into work on day one of the pre-season," Cameron said on Wednesday," Sydney executive general manager Leon Cameron said.
"Having been a standout performer in the VFL over the past two seasons, we think Jai is ready to take his game to a new level and add to our defensive stocks."
