That's right: definitely NOT a Victa.
Hurricane was an Australian Engine and, later, lawnmower manufacturer.
Their engine designs were similar to Victa engines of the day.
The close-up of the decal remnants is a great lead.
I wonder whether it would be possible to get a photo of a wheel side-on,
and of the fuel tank? This would help also.
I date your machine to late 1950s / early 1960s.
They are certainly rare.
Hope this helps.
