I don't know of any local rockabilly bands... for that matter good luck on finding any pinoy bluegrass or country bands, hee haw! But for a good rockabilly workout check out the CD/DVDs of Brian Setzer via his bands Stray Cats and the Brian Setzer Orchestra (which in turn is a fusion of rockabilly and swing). The old Stray Cat tunes "Rock This Town" and "Stray Cat Strut" were revived by the BSO and given a big band treatment.
