Help needed on finding an RTW which includes Delta, Virgin Australia and Etihad

[BoyZeus]

Im searching for an RTW departing ex MEL for July which includes VA,EY and DL - it can be in either Y or J class.

Once I've found the airfare rules I am happy to construct the airfare myself, I just cant seem to find any fare levels or rules out in cyber land...

Mods - does this general question need to be moved to 'Flight Search Assistance' :?:

Thanks in advance.
