have Buckley's

have Buckley's (chance)

To have little to no chance of doing something. Of uncertain origin, it is either a reference to "Buckley's and none" (a pun on the name of the former department store Buckley's & Nunn), or to the escapades of the escaped colonial convict William Buckley. Primarily heard in Australia, New Zealand. I'd say you have Buckley's chance of getting that loan approved.
