Listed in JB Hi-Fi New Mobile Madness Catalogue. Doesn't appear to be listed in the usual spot - https://www.jbhifi.com.au/pages/jb-mobile-instore
$99/month for 150GB/month for 12 months duration.
Not as good as $800 off iphone deal https://www.ozbargain.com.au/node/584475 but still better than usual long running $500 off deal.
Anyone can avail 5% off TCN Giftt cards via Shopback to sweeten the deal. You can choose to receive digital gift cards, you will get an email link leading to sms, follow the prompts and it will give the option to load the cards in google or Samsung pay, which you can use as usual debit cards in store for tap and pay. Better to get HOME TCN cards are they are the onlyone to work in both JB HI-FI and The Good Guys, if you are after tech only.
Don't forget to ask to price match with https://www.ozbargain.com.au/node/600669 if you are after this model or ask for discount, i got $40 discount from JB HI-FI store manager, though he refused to price match Costco.
$10/month credit is expected, to make it $89/month but depends on case to case basis, IMHO.
