"Ms Bell refuted previous assertions by Mr Morrison that he gave himself the powers in response to the COVID-19 pandemic, saying self-appointments to the treasury, home affairs and industry, science, energy and resources portfolio had "little if any connection to the pandemic".

She said Mr Morrison had also instructed his department to prepare a brief for his appointment to administer the agriculture, water and environment portfolio, though he decided not to proceed with it."

The previous Australian prime minister secretly appointed himself to several ministerial positions (which should be separate to avoid an unholy concentration of power tbh). Also, no one knew that he did this.
