I assume these farmers heard the BoM ~19Sept predict for a Brutal Summer and have sold stock thinking they would have no feed.
BoM also called an El Nino on 19 Sept - the SOI Southern Oscillation Index is now positive - ways away from El Nino

Late November rains gave plenty feed - graziers feeling peed - off is understandable.
