Thank you, Rob. As a frequent Vic BDM user, this feature in Sourcer would be an awesome addition.
I don't always understand the abbreviation and in those cases, I don't try to expand the abbreviation. Thus I think you should not attempt to convert the abbreviated location name. In the citation keep the abbreviated location as it appears on Vic BDM and in the Narrative just use Victoria, Australia unless it says At Sea. Then it is up to the user's discretion to expand the location if they can.
My other thought is it would be awesome if you could extract the data from the search list as it does have more information. However, I'm unsure how the user will select a record they want Sourcer to build a source. If you click on a source it goes to the results page and there is no select function on the page at the moment. So it might be easier to build the source from the results page.
