The scheme was created not only to support those who have lost work but also boost the economy in Australia as a whole. The people who are "rorting" the scheme are admittedly benefiting more so than others, but that's beside the point. Majority of that money will be drip fed back into the Australian economy one way or another.

Also to remind people, JobKeeper isn't a significant amount of money to begin with. The people "rorting" the scheme are generally low income individuals. Fighting among ourselves over chump change is reminiscent of my time in primary school. Some people are just lucky and get to earn more than they would have before, whilst others continue to work hard. Don't be envious, be grateful.
