On each downloaded PDF file, Australian Trove has a one-line header with publication details and a footer with the link. Nice because it doesn't take up a chunk of the page, and this would be essential when it becomes possible to download an enlarged version of individual articles instead of the whole newspaper page. The article might be multi-page and would not have the info. at the top each time.

See example:

Examiner (Launceston, Tas. : 1900 - 1954), Thursday 12 February 1931, page 8
