Secondary schooling in Australia and New Zealand

[summerbreeze]

Can anyone tell me how the secondary school system works in Australia and/or New Zealand, please? In particular, I'd like to know what is their equivalent to the UK's GCSEs and A levels and at what age do the children start working for them and actually finish the courses. Maybe there is also an option to do an International qualification in the subjects so that it's easy to compare it to GCSEs and A levels when you go home (to the UK) again? Any advice welcomed. Thanks.

Sorry not sure why link won't work but if you go to the main Port Philip web address www.portphillip.vic.gov.au and go to the 'People and Community' section you'll find the Kindergarten list.

Thanks again to everyone who has posted. I've looked at it more thoroughly and there are some useful links and the posts contain good info too. Many thanks.
