Help (again)

After months of fighting with Optus about the "known" congestion problem on the tower closest to me (I think it's Gilles Plains) They have finally allowed me to cancel my wireless broadband contract with no fee.
My problem now is that Im not sure who to head to.
Is there anyone that lives in or near the Windsor Gardens, Holden Hill, Gilles Plains, Hillcrest, Dernancourt area that can recommend anyone except Telstra for their wireless broadband?
