It's a secret but, if it comes off, Roza Sage promises it will be a drawcard for the Mountains.
The "it" to which she refers is a "large scale music event" which the NSW government is bidding to secure. But the Mountains MP said at this stage she could reveal nothing more.
Mrs Sage did say, however, that it was part of a major funding boost for tourism in NSW, which includes $40.6 million for regional tourism and $22 million to get more events in western Sydney.
"We are taking action now to bring more visitors to the Mountains and I am excited to announce the government is already bidding to bring a large-scale music event to the region," she said.
"We know from experience these types of events bring people in their droves and I am hopeful of announcing a successful outcome once negotiations are complete."
Mrs Sage also said $73 million that has been set aside to make Sydney the number one destination for major events would also benefit the Mountains.
"Our local tourism industry draws heavily on people travelling from Sydney so this focus on major events is a great opportunity for Mountains operators and businesses."
Eric Sward, president of Blue Mountains Accommodation and Tourism Association, said if the Mountains managed to win the "secret event", it would "add another string to our bow".
"I think we are seeing an improvement in tourism generally and currently, on the back of Chinese New Year, we are seeing a short-term increase in Chinese visitors," he said.
He also noted that the opening of the Hydro Majestic had generated added tourism interest.
Jason Cronshaw, managing director of Fantastic Aussie Tours, said if the "event" came off, it could give the Mountains the chance to emulate the Hunter Valley, which hosts several major events and concerts every year, drawing big numbers and tourism dollars.
And Daniel Myles, chairman of Blue Mountains Lithgow & Oberon Tourism, said "we only have to remind people that the Mountains are here and they show up. We saw that with the royal visit last year."
