You need to know the vocab on pages 16-24 of the Latin Continuers Syllabus, which you can download here.
You also need to know the vocab on pages 47-51 of the K-10 Syllabus, which you can download here.
According to the syllabus you are also meant to:
- know prefixes, suffixes and compounds, and common types of word formation
- recognise in context the vocabulary of the prescribed Latin texts
While you're on the board of studies website, you can also download last year's HSC exam papers, or those from previous years if you're really keen. Only last year's paper will have any relevance to the texts we're studying this year, but you may like to look at some past unseens (many of these we've done already anyway).
Enjoy your holidays!
