Correct. For example,
Optus prepaid currently has a 50GB/28 day plan for A$15 (US$10) for the first month, with an eSIM option.
Vodafone has the same although I'm not sure if they do eSIMs. Need more data? Vodafone will do 600GB/28 days for A$65 (US$44). Both have stores in the arrivals area at major Australian International airports (although not necessarily with these plans). None of those plans will have roaming.
