Warwick Stadium (home of the SBL Stirling Senators) is currently being expanded. It will double in size from 4 full courts to 8, and the main court will feature 450 fixed grandstand seats plus retractables.
It's an $8M project. The complex is owned and operated by the Churches of Christ Sport & Rec Association, who are paying $5.5M, and the City of Joondalup is tipping in $2.3M.
Its a little weird considering its the home for the STIRLING Senators (Stirling is the Council immediately to the south.) Warwick is at the southern tip of the city of Joondalup, and this is really the only significant facility in their southern suburbs.
I drove past the other day. Slabs are already down, and it looks like the structural steel is starting to go up.
