I thought I would try "Trewin" in goggle maps and got five hits
three in WA
two in Victoria
Does that make you infamous?
The Ballarat one was a blatant case of the council using all means available to convince my grandfather's company to build a factory there. (The direct family interest in the company is long gone, but the factory is still there). Thought there might be a few more in northern Victoria as there was a Trewin who was a long-serving mid-century Country Party state MP. Can't speak for the WA ones.
Also, on the subject of naming rights, a lot of places in outback Australia got their names from the fact that selling off the naming rights to places you discovered was a good way to get your exploring expedition funded in the 19th century - one striking example being the Simpson Desert, named for the Simpson whose company later became best known for washing machines.
I guess that's better than being named after the last resting place of an explorer named Simpson...
BTW, we noticed last weekend that at Penwortham there is now a corrugated iron cutout silhouette of Horrocks about to be shot by his camel.
Is there anywhere in Australia that managed the same trick as Truth or Consequences, New Mexico
The Perth Trail Series
named one of its events that.
Fun fact - it was my great-grandfather Madigan who gave the Simpson Desert its name!
And the Madigan Line route across it is named after him? Geoff will be interested to hear that :)
A number of the main physical landmarks around Wellington Harbour are (English-)named after the original investors in Wakefield's New Zealand Company: Lord Pencarrow, Somes, Ward, Hutt etc. I don't think any of them ever set foot here. So I guess if all of that mess had happened in the 21st Century, we'd have the likes of AIG Head, Emirates and Mercedes Benz Islands, the HSBC River...
Only until the sponsorship contract ran out, then you'd have to rename it and everyone would get confused as to where you were talking about (I have no idea which states Telstra Stadium and Telstra Dome were in - one in each of NSW and Vic - nor what names they go by today).
Of curse if you are the ABC you don't use the sponsors name anyway.
And they even go to the lengths of referring to a certain Southbank establishment as "a Melbourne casino".
