Abstract
The SABRE (Sodium-iodide with Active Background REjection) South experiment is a direct dark matter detector, made of radio-pure NaI(Tl) crystals surrounded by a liquid scintillator veto. The achievement of ultra-low background rate is essential to provide a model independent test of the signal observed by the DAMA/LIBRA experiment whose claim has not been verified yet. The SABRE South experiment will be located at the Stawell Underground Physics Laboratory (SUPL), Australia, the first deep underground laboratory in the Southern Hemisphere. The laboratory will not only house rare event physics searches but also measurement facilities to support low background physics experiments and applications like radiobiology and quantum computing. The SABRE South detector commissioning is expected to occur in 2023. This paper details the setup and projections for the experiment, and a brief description of the underground laboratory.

Weaknesses
No information about crystals and reasoning why South will use liquid scintillator veto and North not.
Report
In this manuscript author (on behalf of collaboration) describes the setup of SABRE South and presents projections based on simulated background accounted for 50kg crystal mass. The detector commissioning is foreseen in 2023. Second part gives a short overview of the Stawell Underground Physics Laboratory.
The manuscript is clearly written and well organised. It is also suitably formatted for publication.
I recommend the manuscript for publication after some comments.
