Trade-in an old ball for a new NRMA Western Sydney Wanderers football (soccer ball). You can trade in any ball - rugby, soccer, afl etc. Available at all Wanderers home games at Parramatta Stadium and at selected NRMA branches. According to the website the participating branches are at:
Penrith Plaza
Westpoint Blacktown
Westfield Parramatta
Stockland Prairiewood
Westfield Liverpool
Centro Bankstown
Burwood
Macarthur Square Campbelltown
However I know Richmond NRMA is also participating because that's where I got mine from.
I traded in an old soccer ball which wasn't pumped up but the lady said it was fine. The Wanderers ball is red and black with WSW logo, NRMA logo, and "Bringing your football back" written on it. I think it runs until the end of the A-League season in April.
How about a tennis ball?
