Spent the last 29 years of my life living within spitting distant of ysbk, can tell you apart from the odd burnout after dark it is pretty darn quite out here most nights.
Bankstown train station can be another matter, and most of the drive by shootings are nowhere near the airport so generalisations only serve to discriminate and spread fear.
St George cabs are another that will serve the bankstown area, plus I reckon half the cab drivers in Sydney live out this way.
I think the biggest a/c I've seen at ysbk would have to be the HARS super Connie.
