The Waratah Room at Addie Mills Centre is a small meeting venue at 4 Astley Street, Gosnells. City of Gosnells describes it as a hireable meeting room for up to 20 people, with reverse-cycle air conditioning, a security alarm and a basic table-and-chair setup. It sits within the broader Addie Mills community services precinct and is suited to local committee meetings, small group sessions and short presentations that do not need extensive production equipment. The published facilities list shows two tables and ten chairs, which is fewer than the stated maximum capacity; hirers should therefore confirm additional furniture for larger gatherings.
