Our team at the University of New South Wales (UNSW) is searching for transiting extrasolar planets using the 0.5~m Automated Patrol Telescope (APT) at Siding Spring Observatory, Australia. We monitor field stars in pairs of fields (2 × 3 degrees each) at intermediate galactic latitudes (15° ⪉ |b| ⪉ 45°), over runs of approximately two months. To date we have identified 62 planet candidates, though follow-up studies have shown most of these to be eclipsing binary stars. For three remaining candidates a planetary origin of the transit signal has not been ruled out. We are currently analysing follow-up data on two of these. A new CCD camera for the APT --- currently under construction --- will provide higher sensitivity, better image sampling, and up to an 8-fold increase in field of view, increasing our search efficiency accordingly.
