Zane Grey 
Wilderness Trek [EPUB ebook] 

The Australian bush country is as rugged as any terrain in the world. Two American cowpokes, Sterl and Red, found this out when they signed to drive a mammoth herd 3, 000 miles across rough country.—No cattlemen had ever done this before. They knew they were in for a hard time, but they didn’t count on hostile aborigines who knew some strange and unusual ways to kill a man. Sterl and Red found themselves with a lot more at stake than just a cattle drive.
