The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline(${\sim}4$ yrs) light curves for sources brighter than V$\lesssim17$ mag acrossthe whole sky. The Transiting Exoplanet Survey Satellite (TESS) has started toproduce high-quality light curves with a baseline of at least 27 days,eventually for most of the sky. The combination of ASAS-SN and TESS lightcurves probes both long and short term variability in great detail, especiallytowards the TESS continuous viewing zones (CVZ) at the ecliptic poles. We haveproduced ${\sim}1.3$ million V-band light curves covering a total of${\sim}1000 \, \rm deg^2$ towards the southern TESS CVZ and have systematicallysearched these sources for variability. We have identified ${\sim} 11,700$variables, including ${\sim} 7,000$ new discoveries. The light curves andcharacteristics of the variables are all available through the ASAS-SN variablestars database (https://asas-sn.osu.edu/variables). We also introduce an onlineresource to obtain pre-computed ASAS-SN V-band light curves(https://asas-sn.osu.edu/photometry) starting with the light curves of the${\sim}1.3$ million sources studied in this work. This effort will be extendedto provide ASAS-SN light curves for ${\sim}50\;$million sources over the entiresky.
