I think that in a bid to get good use cases out for NEM, having representation from all major sectors of the economy is important. NEM has already proven itself to have solutions in agriculture, big data, intellectual property, supply chain (provenance) and more.
Having a solution in the tourism and the payments industry counts for no less a use case. In fact, an initative like this could lead to many other opportunities. Like what @Trikar_Blockchain said, Australia is being proactive in considering the digital Australian dollar, removing the double taxation issue and many areas within the crypto payments space. If NEM is to use a test-country for crypto payments (and much more). Australia would be well-suited besides other countries which are exploring this.
We need to support good NEM applications with solids teams across the world, especially those who have understood the NEM blockchain technology and want to make this work.
