sleeping bag for OT

Hi all,
I will be doing the OT in late November/early december this and wanted help choosing a sleeping bag as I'm a complete beginner.
I'm looking for a sleeping bag that I can use for the OT & hopefully other hiking trips in Australia & NZ. My budget is a $100 and this is the one I was thinking about. I'm a 5'4" female so the length isn't an issue but I want it to be light and compact.
I really don't know what selection criteria to use other than the weight and my budget. Not sure if my budget is realistic.
This is the one I've been thinking about.Any opinions or recommendations? Please help
