To address your question about the super visa, in my experience many of the people simply do not apply because they don't think they're going to be eligible. Apart from needing to meet the income requirement, you also need to have a lot of cash in order to apply. I think a lot of people simply cannot be bothered. You have a very self-selective process, whereby you tend to get a higher acceptance rate.
On the integrity issue, apart from having to assess the integrity, it is one of the many objectives in promoting visitors, promoting trade, promoting business, and allowing families to visit each other, so let's keep those in mind. But even just focused on the integrity issue...I talked about the consistency in decision-making, which is an important aspect. Victor suggested an interview process, which is also a good mechanism. But how do you change the mindset of some of the visa officers? That is an ongoing challenge, and it's not just about visitor visas in general. Some visa officers have this view that people from certain countries would come and not leave. I'm sure many of you have the experience of dealing with families—I have a number of those cases myself. Someone is ill or has passed away and a relative needs to bring a family member here to attend a funeral or whatnot. The family member has their own family overseas, has a job overseas, has a house overseas, and is still being seen as someone who's not going to leave. I'm not sure what other documents you can require from that person to change the officer's mind. So I think it's really about changing the mindset of the officer, and if we can't change the mindest, then we'd better have a different system in place.
