It seems like only at Harvey Norman stores? Need a new phone yesterday, went to one of the stores yesterday, surprisingly I received further 20% off the discounted $105 promo plan (originally $125) …
As per title. Did this today in conjunction with the $39/month 12 month sim only plan, and used the gift card to purchase a phone outright. https://www.ozbargain.com.au/node/396212
