BUSINESS travellers have driven a $1 million a day jump in tourism spending during the March quarter this year, the industry's national visitor survey shows.
The Tourism and Transport Forum's survey found overnight trips were up 9% during the second quarter of 2014, compared to the same period last year.
It shows the number of nights of travel rose 5% and spending was up 6% during the quarter, year-on-year, while overnight trips and spending both rose 4% for the year ending March.
TTF communications director Rowan Barker said business travel accounted for two-thirds of the increase, with business travellers spending 25% more.
But he said holiday nights in accommodation fell 3%, despite leisure travellers spending 2% more; while those visiting friends and family spent more nights away from home, up 12% and spending 5% more.
The data, Mr Barker said in a statement, showed the capacity of the tourism sector, but more reforms of visas, aviation capacity and investment in infrastructure and marketing were needed.
