It seems that the code is active again.
Please be aware that Woolworths has done quite a bit of work in building a system to prevent existing users from taking advantage of this offer by creating new accounts. I've only managed to redeem the code by creating an account under my wife's profile. If the system finds out that you're creating multiple accounts to redeem this code, your order will get cancelled automatically.

Since it's not mentioned in your descriptions, can I assume:
This applies to Online orders only?
Have to be entirely New users? Or just users New to their online shopping?
