  We present the results of a comprehensive search for stellar variability in
the globular cluster 47 Tucanae. Using the Mount Stromlo 40-inch (1m) telescope
at Siding Spring Observatory and a combined V+R filter, we have detected 100
variable stars across a 52$\times52'$ field centered on the cluster. Here we
present the V+R lightcurves and preliminary investigations of the detected
variables, which comprise 28 Eclipsing Binaries (21 contact binaries and 7
detached systems), 45 RR Lyrae stars (41 of which belong to the SMC and four
seemingly to the Galactic Halo), and 20 K-giant Long Period Variables (LPVs).
We also detected four $\delta$ Scuti stars, one TypeI Cepheid, and one TypeII
Cepheid. One variable appears to be a dust-enshrouded SMC star with a short
period pulsation. Of these 100 variables, 69 are new discoveries. Our eclipsing
binary sample indicates a radial segregation in period, and includes two
binaries that are seemingly orbited by low-luminosity stellar companions. One
RR Lyrae star shows a Blahzko effect with remarkable regularity.
