Ray, the childcare rebate is paid to childcare providers, mostly private businesses. It is not income received by the parents.
As there are not as many childcare places as there are children waiting to go into them, many children are looked after by grandparents while the child's parents are at work.
Of course, there is no childcare rebate paid for this service. The government probably views this as budget savings.
Then the grandparents might be pensioners, so can be considered part of the welfare burden. Neither parents nor grandparents receive any extra income from the childcare package, so there is no extra money to dispose.
Including a government payment to private enterprise as income to a particular family dynamic is a distortion of the reality.
Natural resources are a source of economic rent which can generate large revenues for those controlling them even in the absence of political stability and wider economic growth. Their existence is a potential source of conflict between factions fighting for a share of the revenue, which may take the form of armed separatist conflicts in regions where the resources are produced or internal conflict between different government ministries or departments for access to budgetary allocations. This tends to erode governments' abilities to function effectively.
