Can Australian primary schools study abroad?

Sure, but children going to Australia will have some bad effects and benefits, depending on the situation.

First, the positive impact:

You can apply for an Australian student visa (category 57 1) after graduating from primary school, but you need to graduate from junior high school to apply.

Middle school students can apply for technical courses (category 572) in Australia after finishing high school, and they can only apply after graduating from high school.

The allowed length of language courses has been increased to 60 weeks. Previously, different student visas had different allowable weeks, ranging from 30 to 50 weeks.

To apply for skills courses (572 classes), the IELTS requirement is reduced to an average score of 4.5, while the previous requirement is an average score of 5.0.

The capital guarantee requirement only needs to be calculated in 12 months, while 18 to 24 months.

Second, the negative part:

Before the risk level structure is changed, anyone can become the fund guarantor of the third-level risk level applicant. However, after the structural change, all the funds provided by the level III risk applicant must come from the applicant himself, his spouse, parents, grandparents, brothers and sisters, or his uncle or aunt who lives in Australia and is a permanent resident or an Australian citizen.

This was originally a requirement of Level 4 for fund guarantors, and will be applied to all Level 3 (high-risk countries and regions) after the change.
