New customers only
$200 welcome credit for new customers who join Telstra on a 24 month Go Mobile Plan $95 or above (min cost $2,280) before 31 August, 2015.
Equivalent to $14.58 credit/month over 24 months, making the plan (effectively) $80.42/month
EG:
32Gb Galaxy S6
6Gb Data, Unlimited Calls & Texts - $95/month (64Gb is $102/month for same plan)
Comes down to $80.42 per month, is that cheap ?
