How can my sister apply for a visa to Australia and stay in Australia for longer?

Australian tourist visas can apply for single entry or multiple entry visas according to different situations, and each stay in Australia is three months, six months or 12 months. Usually, a three-month tourist visa can basically meet the needs of passengers. If you need a visa for a longer stay, you need to meet certain conditions. For example, if the applicant's children are Australian citizens or permanent residents, and the immigration application has been submitted and is in the process of application, in this case, the immigration officer will consider approving a longer-term tourist visa. Or if you come to Australia for business, it needs to be extended to 6 months or 1 year.

Australian tourist visa is a visa designed to meet the short-term visit of applicants to Australia. Therefore, under normal circumstances, the maximum allowable stay time of the visa in Australia cannot exceed 12 months.
