This sounds like a good solution. I think the trend is for more jet services into HBA...expanded services from Sydney & Melbourne as well as a new 900m cross GA runway.
From the Hervey Bay Council Airport Masterplan media release 13/3/07...

"The master plan includes provision in the future for more car parks and
security parking, a 900 metre cross runway as well as room for three or
four jets to be parked at a bigger terminal that will cater for the expected
growth in tourism."
This inevitably means more traffic, heavy and light. Most ultralights don't even have Mode A/C transponders let alone Mode S or 1090 Extended Squitter. Figure on a not inconsiderable proportion of the increased traffic being of the ultralight variety. This is no place to have a SSR hole or, for that matter, no place for any aircraft without a transponder...IMO.
