Well, more accurately, it's more difficult if you are married to someone who had income because it affects the means test. Of course, for many of those you can't get them unless you identify and secure a child support order against the parent of your children, and then that child support is also treated as income in the means test for the program, so just staying unmarried (with it without cohabiting) doesn't actually solve the problem.
