%X We observed three AGN from the Parkes Half-Jansky Flat-spectrum Sample at near infrared (NIR) wavelengths to search for micro-variability. In one source, the blue quasar PKS 2243&#8211;123, good evidence for NIR micro-variability was found. In the other two sources, PKS 2240&#8211;260 and PKS 2233&#8211;148, both BL Lacertae objects, no such evidence of variability was detected. We discuss the implications of these observations for the various mechanisms that have been proposed for micro-variability.
