A friend found this on the web:
I've recently created a set of 1:25000 digital topographic maps for Tasmania. I've made them available online for use with a mobile GPS app called Avenza PDF Maps (
https://www.pdf-maps.com/) for Android and iOS. You can download the maps directly to your device from within the app; they will appear when you zoom in to Tasmania. There are 415 maps, with the same extents and numbering scheme as the TASMAP series.
Thought this might be of interest to you guys, with the 25k paper sheets soon to disappear. The official TASMAP digital maps ($2 each) will also work with the app. Smartphone+app seems like a viable alternative to dedicated handheld GPS these days.
The maps were made with my own software (nswtopo) using publicly-available spatial data from theLIST. (You can use the software to make your own maps of custom areas, but it's probably not beginner-friendly.) The maps contain most but not all of the features of the TASMAP maps. Spot heights and some cultural features are missing, but nothing of concern to a bushwalker.
I have downloaded these for free and they are excellent - the normal 1:25,000 Tasmap on your phone.
