The Townsville Chamber of Commerce has backed the Queensland Government's call for better infrastructure to be built in flood-prone areas.
The chamber's president, Dawson Wilkie, says a number of the city's businesses were affected by the closure of Bruce Highway in southern Queensland last week.
He says he wants authorities to look at ways to protect the region's road network from natural disasters.
"The situation is that north Queensland and regional Queensland needs the roads as their lifeblood and what we've got to do [is] make sure that isn't compromised is something we should be looking at," he said.
He says he is concerned that without improved roads, companies might not invest in the city.
"If it's clearly hard that you don't [have] supplies up here because of the floods, that could impact us getting business to relocate up here and that will stifle the growth," he said.
"So it's important we have a good message, that we are well supplied and stocked and it is worthwhile starting a business up here in Townsville."
