School requirements for overseas children

Which are the best education options for these ages? (child care, pre.school, long day care, etc)

At 4 and 2 I suggest long day care for the younger child and preschool for the older one. Your eldest will probably go to primary school at age 5 (depends if the childs birthday is early in the year or later.) day care centers vary in quality greatly. you should not make arrangements without investigating personally.

- What do we have to do to register them in the educational system?
Contact the primary schools of your choice.

Sometimes it can be difficult to find a place in a preschool that suits you. If you know the area you will be living in I suggest contacting preschools in that area as early as possible.

- Do we have to put them in a waitinglist? How long before? There will be a place for your child within the public education system. if you prefer a private school you may need to register for a waiting list.

Depends on the preschool. Some private preschools and schools do have waiting lists.

- How easy is for children from overseas to overcome the language barrier?

Children adapt readily to new languages especially at that age. Its not something to concern yourself with.

- If we arrive to AU in July, Are we still on time to get a place to star immediately? Do you recomend that?
The school year starts in January so it would be wise to contact pre schools to make arrangements.
