Scott Morrison has denied his four day trip through Queensland is the start of a marathon election campaign, saying "this is just me doing what I do."

The Prime Minister mingled with punters at Sunshine Coast’s Corbould Park racecourse, celebrating Melbourne Cup, stating he was in Queensland listening, and most importantly hearing.

Queensland has more than a dozen seats that could turn the election due early next year, with Morrison set to visit five marginal electorates in the coming days.
