Essentially the same deal posted by fozzie last month: https://www.ozbargain.com.au/node/922658
Their web site still leaves a lot to be desired, but hey, if the Vodafone network works for you and 100GB is enough for a year, then this seems to be a reasonable price these days.
EDIT: If you have an existing EzySim service that's about to expire, "Ultimate 12" recharges are currently $119, if you'd rather pay the extra instead of porting out and back in again.
Update Oct 13: e-Sim now $99, physical SIM still $109


Also Lyca doing $110 with international calls and 5g with 200gb.
