If its an area that gets heavy tourism I would build a site or network of sites for tourism in the area. Review sites and Local news updates. I would build my physical business out of the virtual one by building a a quality site and populating it with local businesses and attractions.
It sounds like its all online but you would be reaching out to customers. Initially finding companies with no web presence and offering web design. Companies that have poorly optimised sites I would reach out to and offer marketing and social media services.
If you put the time and efford into your site(s) you will be able to contact businesses for paid directory listings and featured reviews. I say sites because the Gold coast sounds like a big area and you might want to break it down into several smaller resort sites that operate under a holding site.
Just had a quick check and igoldcoast.com goldcoastlatest.com.au and goldcoastupdate.co.au are all available
Probably not what you had in mind but I dont know the area so Im not sure what sells.
Commonwealth games are coming in a few years have you thought ahead on monetizing that ?
