I had the exact same question. From the study guides I've read, there's basically 3 types and they're quite easy to understand. But only revise if you have time to. I did the ATARnotes topic test for Standard Model, and one of the questions were, "Describe the significance of symmetry in particle interactions" (3 marks)
This is what the marking scheme stated:
"Symmetry operations are important as they reveal more about the universe, and provide a foundation for many fundamental laws of nature. They allow physicists to determine a specific interaction will take place, and always conserve both energy and momentum. Whilst violations of symmetry do occur, that cannot be considered laws of nature, these violations only provide further insight into particle interactions. Examples include charge/time reversal and crossing symmetry," - Charlotte Elgey and Tequile Ryan 2021
Honestly, that dot-point is just so vague (typical QCAA). The key is just to provide as much info as you can to maximise the amount of marks in the exam. Having somewhat of an idea of the types of symmetry gives you an edge, as it helps to understand what's going on. However, this will not be directly assessed.
Hope this helped,
