Here are various texts and my opinions on them:
Beck, M., Tatz, P., Lewin, R., Crotty, R., Comans, M., Lyall, G., Breward, I., Johns, A., Kelly, M. Kohn, R. & Pattel-Gray, A. 1997, Exploring Religion, Oxford University Press, Melbourne. [OK but based on Victorian syllabus]
Clark. 2007. Spotlight: Studies of Religion HSC, Science Press, Marrickville. [Excellent for HSC 1U]
Coleman, N. 2006. Spotlight: Studies of Religion Preliminary, Science Press, Marrickville. [Excellent for Prelim 1U and 2U, although the chapter review questions aren't great]
Hayward, P. and Noble, J. 2003. Macquarie Revision Guides – HSC Studies of Religion, MacMillan Education Australia, South Yarra. [Excellent revision for HSC, old syllabus. New one should be just as good?!]
Fleming, Louise. 2001. Excel, Senior High School, Studies of Religion,2nd edn., Pascal Press, Glebe. [Good revision for HSC, old syllabus. New one should be just as good?!]
Lovat, T., McGrath, J., Fletcher, E., and Follers, J. 2006. Studies of Religion. Thomson Social Science Press, South Melbourne. [WAY too brief in each topic for Prelim and HSC 1U and 2U]
Morrissey, J., Mudge, P., Taylor, A., Bailey, G. and Rule, P. 2005. Living Religion, 3rd edn, Pearson Longman, Sydney. [Excellent for Prelim and HSC 2U, especially the "Activities". Quite bulky for 1U]
