bundleplus15
Was moving my power to origin, and asked about their NBN on the side out of curiosity as heard on whirlpool that it's now a white label re-sold Aussie Broadband product (exact same network and support staff from my understanding).
The advertised price for 50/20 unlimited is $74 for origin customers, but they are able to knock it right down to $59 with minimal hassle it seems if you ask for a deal, (ongoing too not just a 6 month discount rate). Other speed tiers with the same $10 customer + bonus $15 discount should presumably be available also.
My confirmation email mentioned the 'bundleplus15' code too so may help if you quote that or the like.
Edit: May be harder to get for existing customers according to comments, and some reps don't seem to know about the deal/won't offer less than $64 for some.
Note: White-label Aussie Broadband customers can not opt-out of Aussie's CG-NAT, and IPv6 isn't available for them either at present, so if you care about either of those be warned.
Feel like their energy prices are a bit jacked to make up the balance here but could be wrong.. electricty pricing is so far someone just making up random numbers in my opinon.
