The Transiting Exoplanet Survey Satellite (TESS) will provide high precisiontime-series photometry for millions of stars with at least a half-hour cadence.Of particular interest are the circular regions of 12-degree radius centeredaround the ecliptic poles that will be observed continuously for a full year.Spectroscopic stellar parameters are desirable to characterize and selectsuitable targets for TESS, whether they are focused on exploring exoplanets,stellar astrophysics, or Galactic archaeology. Here, we present spectroscopicstellar parameters ($T_{\rm eff}$, $\log g$, [Fe/H], $v \sin i$, $v_{\rmmicro}$) for about 16,000 dwarf and subgiant stars in TESS' southern continuousviewing zone. For almost all the stars, we also present Bayesian estimates ofstellar properties including distance, extinction, mass, radius, and age usingtheoretical isochrones. Stellar surface gravity and radius are made availablefor an additional set of roughly 8,500 red giants. All our target stars are inthe range $10<V<13.1$. Among them, we identify and list 227 stars belonging tothe Large Magellanic Cloud. The data were taken using the the High Efficiencyand Resolution Multi-Element Spectrograph (HERMES, R $\sim 28,000$) at theAnglo-Australian Telescope as part of the TESS-HERMES survey. Comparing ourresults with the TESS Input Catalog (TIC) shows that the TIC is generallyefficient in separating dwarfs and giants, but it has flagged more than hundredcool dwarfs ($T_{\rm eff}< 4800$ K) as giants, which ought to be high-prioritytargets for the exoplanet search. The catalog can be accessed viahttp://www.physics.usyd.edu.au/tess-hermes/ , or at MAST viahttps://archive.stsci.edu/prepds/tess-hermes/ .
