Everyone is different some rely on it fortnightly for that exact reason, others can have it all in a lump sum. My DH is a farmer and it is hard to estimate his income so it is safer for us to receive a lump sum. I find that the lump sum then helps us to pay for things throughout the year until the next payment comes.

It is just good that people have different options, it doesn't have to be all or nothing, you can choose to get some fortnightly and some in a lump sum
