Books like Wallaby Track

I read this series of 5 books while visiting Australia. This is book #4. I enjoy learning history through historical fiction. I am going to leave the same review for all 5 books. I enjoyed the first two books because I felt I learned quite a bit about the aborigine culture, the transportation of convicts to Australia, and the beginnings of the giant sheep stations. However, I found the subsequent three books not as good. The author basically used the same boy-meets-girl formula as a focus in the final three books, and there was not as much history to be gleaned. In fact, I skimmed quickly through the "romance" scenes because they got rather abnoxious and over the top.
