The one month is free (you will need to provide credit card details.)
I would suggest you create your new Netflix account on a PC (So take the 1 month free option). Much easier to set up. Then you just punch in your username and password into fetch and you are away. You'll only ever have one Netflix account regardless of what offers or options you use with it.
Its very easy to manage your fetch account online. A big option to suspend your account is readily available. You will be billed the next month ($12) if you don't exit before 30 days but its a month to month contract so the worst you'll be is $12 down.
As a bonus you can exit your account as soon as you set it up. Netflix will confirm you will not be billed anymore but you will still have access to any remaining days (i.e. the 30 days)
As for the 6 months offer, You'll have a voucher that will add 6 months to your current account (its related to Netflix, not Optus). Note Optus do say:
Make sure you claim your voucher for a code within 14 days, or they'll no longer be available. All the voucher codes will expire at midday on September 30, 2015
So it seems you can use the voucher (within 14 days) to get a Netflix code. You can punch in the code to Netflix account anytime up to Sept 30.
So sign up on the free 30 day account and just add in this 6 months to your existing trial account account (Seven months )
BTW Optus says 'up to' because different customers get different amounts of Netflix. Prepaid phone customers will get only 3 months for example.
Unless you want to watch Netflix simultaneously on 4 devices, spend the next six months finding a mate who will go halves with you in Netflix. Netflix make it very easy to setup multiple profiles (one for you and one for the kids for example.) So you set up a profile for you and a mate and when you log in to FetchTV you just select your profile and you're away.
