Casual work?
The only genuine 'work from home' opportunity I know about is working as a route checker for Deya Ltd. Details of that work (and registration for casual work, such as delivering directories) can be found here:

(I team lead directory deliveries for Deya)
I also do casual delivery work for PDC:

If I'm desperate, I might consider working for TNT (who pay peanuts):

I'm also regional supervisor for CTS Traffic & Transportation (who carry out roadside traffic surveys and related work):
