Thanks Ditzy;
I didn't realise that QF Business lost $$. However, it must be better now that QF are now the sole supplier of Premium seats in this country.
My wife and I sometimes (rarely) use QF Business domestically.
Personally, the centre seat of an A330 would not worry me - but overall, if the standard of service in Business fell and the difference between Economy and Business became 'blurred' then I would choose Economy with a Qantas Club membership.
