I heard about torrential rains and flooding in parts of the country. The good news is that I guess this means the drought is over or at least has put a serious dent in it.
I bought a dehumidifer a while ago (used DeLonghi- Trademe - $120). I googled to find out what is a healthy humidity inside a house and found this:
"Humidity levels below 30 percent are considered dangerous for people and other household contents. Humidity above 75 percent can encourage the growth of mold and bacteria. The ideal range for indoor humidity is 40 to 60 percent".
Posting it here in case other members have the same question.
