These two deals are currently available in store only if anyone interested. Not displayed or advertised anywhere. Good lad served me and advised well.
I have just grabbed the $69/80GB deal with $400 gift card at JB Hi-Fi Forrest Chase in Perth and successfully applied a $10 per month credit discount for 12 months through the telstra chat :)
Update: the deal with $400GC is still on thanks to raiyani
