MINERVA-Australis: Two years of TESS follow-up

MINERVA-Australis at the University of Southern Queensland's Mount Kent 
Observatory is the only southern hemisphere precise radial velocity 
facility wholly dedicated to follow-up of TESS planets.  
MINERVA-Australis is a partnership between MIT, UNSW Sydney, George 
Mason University, University of Louisville, Nanjing University, 
UC-Riverside, University of Texas, and the University of Florida.  
Observing time is also available to the US community via NSF NOIRLab 
proposal calls.  Being fully robotic, we have been unaffected by 
Covid-19 closures.  We have contributed data to the validation of 23 
TESS planets.  I give an overview and update of operations, highlighting 
our recent mass measurements for TOI-778 and TOI-1842.  I also describe 
our new photometric capabilities, aiming to validate small TESS planets 
and to rescue planets from ephemeris erosion.
