How do you spell Koo-Wee-Rup?

What's the correct way to spell Koo-Wee-Rup?  Any way you want apparently. The article below, a letter to the editor of the Kooweerup Sun written by Mr C. Einsedel, suggests that Koo-wee-rup or Koo Wee Rup are the most acceptable. The way I usually spell it, Koo-Wee-Rup, is 'an absurdity' according to Dr Niel Gunson, historian and author of  'The Good Country: Cranbourne Shire' a history of the Cranbourne Shire,  published in 1968. It is a book that I admire and use frequently.  

Kooweerup Sun (that's how they spell it) March 21, 1973.

I was interviewed in the Pakenham Gazette about this very issue - here is the article from April 3, 2013. What I said was that my Birth Certificate has the town spelt as Koo-Wee-Rup and Kooweerup and that various documents from my time at the High School in the 1970s has the name spelt as Koo-wee-rup, Kooweerup and KooWeeRup, so  even Government organizations were having a bet both ways.

VicNames - the Register of Geographic Names lists it as Koo Wee Rup. You can access their website here https://maps.land.vic.gov.au/lassi/VicnamesUI.jsp

Whatever it is,  I believe that it should be three words. I agree with Dr Gunson as quoted in Mr Einsedel's letter that running the word together is a 'mark of laziness'.
