I found this googling around:
https://www.iseekblinds.com.au/plantation-shutters
They start from $250 per square metre (excluding installation).
Also these:

It's hard to tell without entering a lot of info, but it looks like around $500 to $1000 per window.
Are these prices normal? Does anyone have experience with DIY installing these? Advice?
I'm pretty handy, and I'd like to DIY.
(But also very busy, so if installation is less than what it'd cost me in time, I'll pay it).
i've bought off i seek blinds.com.au before. quality is quite goood and installation isn't too hard either. i would probably not diy any large windows though, i have one of my larger windows (280x100cm) ordered through them and the panes aren't straight/close properly.
