Teaching you can pretty much work in a child care centre or kindergarten. If your degree covers 0-8 year olds you can also teach the first few years of primary school. Non-teaching there are jobs in early childhood management such as long day care directors or accreditation supervisors.
That depends on the degree she is studying. My degree is only for teaching 0-5's.

You can also do an adult teaching course as extra and be a tafe/college teacher.
