Best accurate maps for Mt Glorious and surrounds?

Hello,
Just wondering if anyone has any suggestions for map resources for this area? Or which hiking books might have 'the trails less taken' listed?
I did Northbrook Mountain today but noticed a little side trail that doesn't appear on any of the Dept of Parks and Wildlife maps. After some googling I discovered it leads down into Northbrook Gorge. I had the same experience with the Piper Comanche trail - not on any official maps but was able to figure it out by using other people's directions or all trails data. I don't mind a bit of investigating for a good hike but I don't really like relying on all trails as people often 'go their own way'.
I have had a look on Avenza maps and Qtopo but can't find trail data for this path.
Thanks
