Bonus $200 JB Hi-Fi gift card on the Telstra $69 plan, that's already available with $300 of JB gift cards.
Brings it to a total of $500 gift card and net of approximately $27.33 a month.
Staff member told me that they weren't allowed to advertise the deal (looking around the store, this was true) because Telstra wanted them to sell more of the $99 plans. Also mentioned that it was available today only (28 June), but he may have just been trying to put the hard sell on me.
Seems to be available in all stores. Updating to 30 June based on what people are saying below.
Mod: Some users have reported a $10/month port in credit after some effort/attempts on live chat.
