In Australia, education is compulsory for all children between the ages of 6 to 17 (Tasmania 5-16 years) either in school or registered to homeschool. Once enrolled, children are required to attend school each day it is open for students, with occasional absences being allowed on justified grounds (eg. sick, medical, urgent family, religious).
In regards to travel, families are encouraged to plan for this during school holidays, however in some circumstances students may be eligible to enrol in distance education for travel periods over 50 school days.
Most teachers of primary school aged children will accommodate parents wishing to take their kids out of school for a few weeks for a trip. At this age, educators recognise the importance of giving
young minds the opportunity to explore and experience different environments and lifestyles as much as possible, plus they recognise that sometimes learning in context from parents in real-life situations is just as valuable as in the classroom - and sometimes even more so.
For older kids, your school may not be able to cater for your absence. Generally each state operates its own Distance Education Scheme. Talk to your school principal
well in advance and seek their advice and referrals. Don't leave it to the last minute. Start with looking at the
Australian Government's website and follow links.
