Jake,
Both Kingaroy QLD and the Northern Rivers Casino, Murwillumbah, Lismore, Byron Bay, Ballina and Border Loop ones are quite long and offer variety. Add a few more modern day industries to both and enjoy. See what types of industries you prefer and either add or modify existing ones.
The Brisbane Valley one is quite useful especially if you update it to present day by adding a few modern industries. Merge the Port Of Brisbane with the other Brisbane Cleveland route that also includes Acacia Ridge and the only limit is your imagination.
Cheers
Peter
