Qantas Frequent Flyer - QF23/24

Hi

What can I expect in business class on QF23 and 24 from Sydney to BKK (return?) in December/January?

Is this Sky Bed Mk1 or Mk II or something even worse?

Is business worth it?

Thanks all!

I am going business class on these flights in September. Why does anyone fly business, access to the lounge, bigger seats, better food, better service, priority boarding... the beds are sloping, but going over is a daytime flight, coming back is night, but only 9 hours, so how much sleep do you get anyway.
We are going on a business trip so it is a business expense which makes it more affordable as a third of the cost comes off our company taxes - sort of. Up to you... I never fly better than premium economy for personal flights, but I don't think that is an option now with these flights.
