Google Maps plugin > create based on Australian postcode

Hi there,

I have created a number of pages for a client - a plumber - each past is a suburb within my client's service area. I now want to insert a Google Map (hopefully insert by batch) on each suburb based on the postcode (Australian postcodes are 4 digits, for example 2000 is the centre of Sydney, NSW, Australai).

Is there a plugin that will allow me to do this?
