Abstract
Observers from Australia and New Zealand used video equipment to time eclipses of short-period binary stars. The objects were typically south of -20o declination and had periods of less than a day. Many of those systems had very few observations since their discovery and some of them had not been observed for 50 or more years. We present 44 times of minima of 42 stars, provide revised ephemerides for 7 of these systems and characterize an orbital period change for RW PsA.
