2-4 night hike... Where to go? (Anywhere in Aus)

Hi guys,
I am sure this topic has been covered a million times, but in early November, my husband and I are looking to undertake a hike from 2-4 nights.
I haven't done much hiking before, and am a little unfit, however my husband is very fit and experienced.
We are located in the Blue Mountains and have done numerous day hikes, but we are looking to fly somewhere and undertake a hike as a trip away.
My husband has suggested the Overland Track, which looks spectacular, but I'd love some more suggestions.
We have also considered zipping over to NZ for the hike, so will also consider any spectacular hikes there.

Thanks guys!
