Good 4-Day Walks?

Hi,
I'm in a group looking to complete our Gold Duke of Ed Award in the summer holidays but we've had difficulty finding an appropriate 4 day walk.
Any suggestions?
btw it can't be the Yarramalong to Mt. Wondabyne Station section of the Great North Walk or the 6ft track as we have already done these.
