Sydney Sirens is a netball team based in Greater Western Sydney, Australia. They play in Suncorp Super Netball.
Originally named Giants Netball, they formed in 2016, when the ANZ Championship was disbanded and a brand new Australian netball league was developed. The league was designed to include the 5 Australian teams who had competed in the ANZ Championship, as well as 3 completely new teams. Giants was founded as a joint venture between Netball New South Wales and Greater Western Sydney Giants, an Australian rules football club.
For the 2027 season, the Giants were transferred to new owners and rebranded as Sydney Sirens.
