Seems to be available in multiple colours and sizes. Also in stock Australia wide so Click & Collect is very much an option (no stores in TAS & NT).
I bought the Speedway Creme recently for on sale for about $120 and I really dig it. The strap buckle is magnetic and clicks super easly so there's no fiddling with putting it on.
If you want a better view of the helmet and colours, the Thousand website has a 360 degree view of each colourway if you scroll down: https://www.explorethousand.com/products/bike-helmet.
Carbon black seems to be a favourite for obvious reasons among buyers- the white one shows marks very easily and is annoying to keep clean.
How much for just one?
