Sales and marketing manager David Ovendale declined to give actual visitor numbers for its Coronet Peak and Remarkables skifields, citing commercial sensitivity.
"The numbers are very good, and we appear to be managing to reduce the peaks and troughs. The numbers have been consistently strong every day," Mr Ovendale said.
Statistics New Zealand figures showed Australian visitor numbers were up 9.2% in June, with those listing "vacation" as reason for travel rising by 20%.
"I would say most of those on vacation from Australia in June would be visiting our skifields," he said.
The influx of Australians had provided a "glimmer of light" during the economic downturn.
NZSki had marketed to Australians in conjunction with Tourism New Zealand and the Ski Tourism Marketing Network, he said.
Destination Queenstown chief executive Stephen Pahl said the local business community had shown "significant foresight" by investing an additional $1 million in 2007/08 into to target the Australian market.
"The extra $1 million funding has had resounding results and we are delighted," he said.
The organisation would spend half of this year's marketing budget in Australia.
Australian hits on Destination Queenstown's website were up from 40,321 last year to 78,659.
Ministry of Tourism figures show international visitor arrivals are forecast to grow by an average of 2.5% a year over the next seven years, reaching 2.9 million by 2015, up 18.6% on present figures.
Ministry research manager Bruce Bassett said the forecasts had been revised back from 4% because of the global recession and the H1N1 pandemic.
The strongest markets over the forecast period are expected to be Australia and China, which are expected to provide two-thirds of the total growth.
