Noted. I'll incorporate this feedback in the next edition (circa end 2022 or early 2023).

The large month to month swings are because the Australian labour market isn't so big, so even a single employer's hiring spree can significantly affect the number of listings in a given month. There are seasonal effects in there too of course. It's volatile data.

I did a quick mock up using a general additive model, which I think's a better fit. I'll use it next edition: https://i.imgur.com/7oTn9Oq.png
