Yes, I believe that is still the case. From 28th April the rules change and no test is required after this date. "If you are a fully vaccinated international arrival entering Queensland, you must get a COVID-19 test within 24 hours of your arrival in Queensland and quarantine at your residence, accommodation or boat (leaving only if necessary to obtain a COVID-19 test at an approved Queensland Government COVID-19 testing centre) until you receive a negative result."
