Businesses say the new Coalition government will herald a golden era for southern Queensland.
It campaigned on a $700 million promise to start building Toowoomba's second range crossing.
Toowoomba and Surat Basin Enterprise CEO Shane Charles says Prime Minister-elect Tony Abbott's decisive victory on Saturday means work will begin by Christmas 2014.
"You little beauty - it is fantastic for this region," he said.
"Toowoomba won't know itself in a few years' time."
Mr Charles says the past three years of minority government has not been good for business.
He says Mr Abbott's big election victory will boost confidence.
"What we've been seeing in a number of sectors [is] that there's uncertainty in spending and uncertainty in our national governance," he said.
The Coalition is also promising to build a multi-billion-dollar inland railway from 2016.
The line would cut through Charlton, west of Toowoomba, where John Dornbusch's Interlink SQ is building a major road and freight handling facility.
"The largest component of it is the proposed tunnel through the range up to $3 billion that money has to be spent in our area and that's really important for us," Mr Dornbusch said.
He says there is lots the new Government can do to help small business.
"Business people want the government foot off their throat and the hand off their wallet," he said.
He says both projects will boost the local economy.
Meanwhile, the LNPs returned member for , Bruce Scott, says his first priority under a Coalition Government will be to improve the live cattle export trade.
Mr Scott comfortably retained his seat over the weekend and has started his ninth term in Parliament.
He says he will be able to achieve more for western Queensland now the Coalition is in power.
"Getting rid of the carbon tax and being able to deal with the debacle of the northern cattle industry that the Labor Party destroyed are two key issues for myself," he said.
"I think once we can deal with those things and get the budget in order, I think we'll start to see business confidence return.
"First of all I think it's going to be an injection of confidence into the business community and the general public.
"Of course a great opportunity for our people on the land to get better prices for their produce, including getting live cattle exported into Indonesia again."
