Grant for Scans?

As a family historian, I am looking into the WW1 Internment of George Otto Tummel and Willhelm Rudolph Tummel. These documents are scanned and available in the NAA https://recordsearch.naa.gov.au/SearchNRetrieve/Interface/ViewImage.aspx?B=443830

THANK YOU!

I would like to look that the 4th Military District Intelligence Records for this era to get more background.

However a whole week is nearly $225!

Is there another mechanism to get these scanned for posterity? A Grant or something?

Thanks

Nick
