The old Maryburg is not that much of a tourist destination, kinda the sad old Boiler Aunty to Hervey Bay & Bundy (Don't even mention the Sunny Coast just down the road).
But ...not too far out of the old Maryborough is a pretty smick new jail with the obvious incumbent prison population. Captive market, so to speak.
Prisoners need to get to and from, and those that love 'em samo.
Could work, hope it does.
