Abstract. The Automated Patrol Telescope, operated by the University of New South Wales,
has been undertaking a search for extrasolar planets using the transit method. We present
lightcurves from two recent promising candidates; spectroscopic follow-up using the ANU 2.3m
telescope shows that the companions are probably low mass stars rather than planets, although
more data will be needed to be certain. Additionally, we outline future improvements to our
transit search: a hardware upgrade scheduled for 2006, and the addition of a robust trend-filtering
