The cheapest plan at every amount of data
For each amount of data a month, each provider's cheapest plan with at least that much, priced a month once any intro deal ends; the dashed line is the data the page is on. A line steps up where a provider's next plan starts, and stops where it sells nothing bigger. Year-long plans count at a twelfth of the year.
Cheapest plan with 40GB or more a month, once any intro deal ends: Boost Mobile $53.23 a month (Telstra’s network); Optus $54.32 a month (Optus’s network).

Each row says which figure is lower or higher; it doesn't say which provider suits you.
