g'day tom,
a hard question to help with when we can't see the situation. yes you
need to work out how or where the water comes from or gets there?
french/agricultural drains (have some ideas on them on my page) will
work if you have or can create somewhere for the water to drain to?
also a simple thing like adding another good layer of top soil can
alleviate pooling problems.
