A lower aussie not only makes it cheaper for foreigners to visit but makes staycations for locals more attractive, as hard-earned cash doesn't go as far overseas.
Aird said discounting New Zealand, the bulk of Australia's international visitors come from China, with short-term arrivals increasing more than 21 per cent in 2014/15 compared with the previous year.
He predicts one million Chinese will holiday Downunder next year as household incomes rise.
The number of holidaymakers from the UK and US are also tipped to increase as their economies recover and currencies strengthen.
Tourism is Australia's third largest export - bigger than the agriculture sector - and brought in A$43.4 billion ($48.4 billion) in 2013/14.
It also employs around half a million workers, which represents 4.6 per cent of the total workforce.
It is the nation's largest services export as the services sector becomes a major economic driver of growth following the mining investment slowdown.
And while all regions will cash in from the influx of travellers, states most geared to tourism like NSW and Queensland will benefit the most.
"The Barrier Reef has been a major drawcard for international tourists while Sydney Harbour is one of Australia's iconic places," Aird said.
"Since the Australian dollar started heading lower, real spending on hotels, restaurants and cafes has lifted considerably."
He said robust growth in Queensland's tourism industry is working to offset local job losses associated with the resources downturn.
CBA expects the aussie to drift lower during the next 12 months and, as a result, the tourism industry's contribution to growth is set to rise in the next couple of years.
