In true OzBargain fashion, I stumbled across this deal whilst looking for something else.
Well reviewed wireless mouse. Unfortunately, white is not on sale. This appears to be the cheapest I have seen, previous deals: https://www.ozbargain.com.au/search/node/Razer%20orochi%20v2...
Usual price is from $110-120. Shipping for me was $9.90, it might be a little more to regional areas.
Out of stock at PC Byte.
Added new link to EbayPlus, has both white and black in stock for $89.66 (with code PLUSSP22) . Thanks to azukay.
