Unlike the three other deals earlier today on what sounds like the same Corsair Vengeance RGB Pro 32GB 3200Mhz RAM, this is the CMW32GX4M2C3200C16 model with tighter timing (16-18-18-36) and at least in my case, confirmed compatibility with my MSI X570 motherboard.
Looking online, this particular set is still running around the $290 mark so Amazon AU is doing a decent price this time. Note that it is "Ships from and sold by Amazon AU" - ie. not Amazon US via AU but actually fulfilled locally.
Interestingly this only came to my attention as I was researching and it's actually the same item as what I previously posted a few months back but fifty dollars less: https://www.ozbargain.com.au/node/475986
EDIT 30/11 Unfortunately the price has gone back up to $266.96 + delivery as it's no longer fulfilled by Amazon AU.
