Repost of the previous deal (https://www.ozbargain.com.au/node/506169):
Pretty good deal, only $3 more than the 200GB plan. Month to month contract is a nice sweetener.
Save yourself some $$ and get a modem from 2SG instead of Optus (https://2sgwholesale.com.au/product/huawei-b525-4g-router/).
(PS, I asked for an extra 20% off the 200GB plan for 24 months, which they gave without any issues via the Optus chat)
Minimum cost over 24 months is $1632.
