Their $22 weekend (Fri-Sun) lineup includes seafood items. From memory, the weekday lineup (sans seafood) is $20.
googling a little further, i found a few other options that i hadn't previously known of (or maybe had come across but just forgot about).

this restaurant was previously known as Oshin. i've probably only ever been to it once (if ever), and have always had the impression that this was a pricier place. having said that, their buffets don't sound too bad in comparison to the others on this page.
Wednesday dinner sushi buffet $25
Sunday lunch or dinner shabu-shabu/sukiyaki buffet $25
- Tibetan Kitchen, 1/59 Hardgrave Road West End, 07 3844 7355
"for tables of six or more all-you-can-eat banquets are available" - there's no further info on their website about this, but i asked by phone and was told it is a $24 per head menu featuring a selection of entrees, breads and mains (the most popular ones) from their menu
