Simple, you cannot compare Singapore Air with Qantas. But I agree with you about what a terrible business decision QF has made.

Total rip off as you would expect! They could all learn from New Zeland's "Telecom" NZ$6 per day for unlimited data (fair use policy) for roaming in AU and NZ$10 a day for UK, USA, China, Singapore!!!  If they can do it, why can't AU providers????

I wonder if they will keep both the lounges in Auckland?? Emirates is amazing compared to Qantas.
