Edit: This deal really kicked off and they've received a large number of orders from OzB. I have received the following email from them, "We're sending out all the Cascades we have, but yours may be delayed depending on what time you placed your order. Don't worry though, the next shipment of Cascades will be arriving in 3-4 weeks, so delays will be kept to a minimum." If you place an order now, expect to wait a while for it.
If you're looking for something to arrive sooner, perhaps look into the following deal for a similar chair at Winc: https://www.ozbargain.com.au/node/554561
