Kogan Mobile's everyday price has dropped from $120 to $109, and the data has increased from 60GB to 80GB. Price is equivalent to $9.08/month, with 6.67GB a month (but the data isn't rationed per month, you can use all 80GB in the first day if you want to).
The carrier network is Vodafone (which was bought by TPG, so should it be called the TPG network?). Esim is also available. Kogan appear to be rolling out VoWiFi and VoLTE according to comments on Whirlpool: https://forums.whirlpool.net.au/thread/9j0n7k09?p=111
This plan does not have free international calls. International calls can be at per-second rates, or you can purchase an international call pack. This plan can be used when roaming overseas if you pay the very expensive $15/24 hours roaming fee.
This deal has been listed on Kogan.com.au as well as on KoganMobile.com.au. If you purchase through Kogan.com.au, discounted Kogan gift cards should work, according to previous deals. If you want to do this, check the previous deals, they said something about adding the gift card to your Kogan account BEFORE purchasing.
Warning: if you renew this plan before the 365 days are up, you forfeit the remaining days in your existing plan, and any remaining data allowance. Data DOES NOT bank with this plan. Renewal will cost $109 unless they drop the price further.
If you're willing to wait, Kogan discount this plan to $99 a couple of times each year. Sometimes they also give bonus data. Also, consider that MVNOs using the Optus network often discount their 365-day plans to $89 for your initial subscription, and sometimes have cheaper recharges (e.g. Coles Mobile). So this plan is really for people who want to use the Vodafone network, perhaps because Optus has poor coverage at your home or at your workplace.
