Just because I find this conversation to be completely absurd I thought I would waste 60 seconds to do a search. While SYD might be a very tough redemption and that has been discussed here many times I put in a random date for a one one biz award from BNE and on my VERY FIRST search I found 2 seats on March 8 from BNE-DXB in business.
I have zero loyalty to EK and in no way am I trying stick up for Emirates here but this discussion is so obnoxious, anyone who uses miles and hangs around flyertalk knows you need to be flexible, take position flights, ect to get what you want. Stop complaining, be flexible and buy a $100 ticket to BNE to get your Emirates award.
