These camps are not merely emergency housing; they are detention centres. Refugees should not be put in detention; they are not criminals.Firstly, there are not adequate facilities. Detainees are denied proper access to medical services, legal services, communications etc.
Secondly, if you can't see what is wrong with putting refugees in camps and denying them basic freedoms then you need your head examined.

Provided there are adequate facilities what is wrong with putting applicants in camps as described.
In 2013 the UNCHR did report that conditions were cramped and in some cases a lack of water. This would not be acceptable. Recent reports would be interesting. There is nothing wrong with putting asylum seekers into processing centres, but they should be able to accommodate the numbers coming in.
These people have human rights.
