Cowra NDB is high work load in the soup I will second that! Bathurst NDB is the best for renewals 3 mins outbound (from memory) plenty of time to get it all sorted and to top it off pretty much RWY aligned. I have heard pilots speak of NDB approaches around TAS that are pretty hairy on a good day
Going to miss the days of an NDB approaches but an RNAV is just as good as an ILS and is much better for the air switch so operators love it!

The old NZMO (Manapouri) NDB approach used to renowned as one of the toughest... not sure if it's still the same as it was way-back-when... many years since I've flown it -or even thought about it!
My favourite is the Alice Springs NDB (in the old days it was called a twin locater, I think) to circle rwy 30. In a Cat C aeroplane with one serviceable ADF. A few traps for the unwary.

Built in errors!!!
Alice Springs had an approach which I think was called a"twin NDB" approach for a short time.
The chart showed it as a straight line approach using two locators and the NDB. The only one in Australia using three aids.
The problem was that the two locators were aligned with the runway, and the NDB was not. So we actually had a bent approach which was shown as straight. There was a built in 4 degree error.
This approach was almost unflyable within normal tolerances, and was quickly changed after a westwind freighter had a CFIT one night, killing three pilots.

RadioSaigon the approach hasnt changed much at Manapouri, here is the link:

Id say you would get dizzy on this approach if you had to go missed.
Can you imagine this in a low performance aircraft! 
Here is a Twin NDB/DME approach for Dunedin, which actually uses three NDB's if you include the missed approach...

hehe yup S.E.A.L.11 that's it orright! 
She's a purler!
Yeah have had the dubious pleasure of shooting the BE Twin NDB/DME into NZDN many times. Don't miss it at all, strangely, especially in a howling NW with a 4,000' FZL!

VLI 11 VOR DME NDB.
Yes you use all of them if you fly the full shebang. Out bound on a VOR radial DME arc around to a Inbound NDB bearing to bring you in on a base.

No argument from me re SW though. That place is fierce.
