Third-Party
I saw that Catch.com.au offer of 10% on CashRewards was conditioned by categories. 'Home Entertainment' is 10%, despite not being a category on their website and is listed in the 1% category as well with electronics & games. What does the 10% apply to?
Home Entertainment appears to be a sub-category within Electronics. There is no shortcut on Catch's navbar that takes you directly to this category, but you can get to it by using the breadcrumbs links whenever you view any LCDTV listing.

I would contact CR and get them to confirm before buying anything (and keep the chat transcript in case they don't honor the 10% cashback)
