GPS mapping

["LEW DAILEY" <>]

I will be spending 4 weeks birding in Australia in March/April of 1999.
During my birding in the United States my companion and I have used GPS and
the computer program Street Atlas USA to assist with navigation. Is anyone
familiar with the use of GPS in Australia and if there is a similar type of
computer program for Australia?

Also, I'd be interested in some responses as to which identification field
guide I should purchase as this will be my first trip and the number of new
birds is rather overwhelming.
