Further education (education once
you have left school) is VERY popular in Australia.
You can do university courses part-time/full-time if
you can prove you got a sufficient level of education
in your country of origin (have certificates/diplomas
evaluated and translated).
Likewise you can go higher into Graduate Diplomas and
Post-Graduate studies. There are some EXCELLENT distance-learning
courses that are as good as or better than their campus-based
counterparts. It depends on the university.
For people who like less of a commitment, you can go
to the TAFE, which is geared
towards more vocational skills. You can study almost
anything on earth, there is no point giving you a list.

You can join workshops at your local
community centre (cheap) or attend classes in private
institutions (expensive). Local community centres
usually have language courses if you need to improve
your English. You can find their numbers in local papers
and pinned on bus stops, cafes, etc...
