"My number one priority is more funding for our roads and more funding for rail," Mr Tehan said.

"In particular we have to make sure the Princes Highway corridor strategy is implemented and we have to make sure we get our fair share of the $1 billion allocated for the highway for south-west Victoria."

Mr Tehan said voters had a very important decision to make on election day.

"The Morrison government has an economic plan for the nation's future which includes cutting taxes for small businesses and families and the largest infrastructure campaign in our nation's history - $100 billion over the next 10 years," he said.

"We've already seen the benefit of that with investment into local road and rail."

Mr Tehan said a vote for the Morrison government would also ensure continued record funding for health, education and disability services as well as investment into local communities.

"That will be contrasted by the Shorten Labor government which wants to impose $200 billion worth of new taxes on the Australian people," he said.

"This will suffocate the Australian economy and set back all the progress we've achieved in the past 10 years."

Mr Tehan is one of three candidates who have put their hand up in the electorate of Wannon.

Camperdown's Josh Wallace is standing for Clive Palmer's United Australia Party, while Stawell's Maurice Billi is running as Labor's candidate.

In the past few months Mr Tehan has promised more than $85 million to various projects in the south-west.

The biggest announcement was $80 million for south-west roads, including the Princes Highway West - from Colac to the South Australian border, the Henty Highway, the Portland-Nelson Road and the Portland-Casterton Road.

Other funding announcements include:
