The best physics textbook for HSC is Jacaranda, i have this HSC magazine that shows some of the highest achievers in the state for each subject, and the majority of the highest achievers for physics used Jacaranda as their textbook. But seeing as though you already have the pdf for that, you should probably get a study guide of some sort. To be honest, i think Success One HSC is the best because it is a collection of past papers for each year, and the book is really structured well as it contains past HSC questions topic by topic.
