Both Dutch natives and EU-migrants are to be paid minimum wage, however it is a common trick when hiring migrants to charge them a ridiculous amount of rent for very sub-par accommodation nearby the jobsite. For example €600/month for a bunk-bed in a room with eight others. That is a way many temp agencies earn extra from migrants.

In theory, yes, but I know a decent number of my own countrymen (Serbians) that most definitely aren't legally employed in NL, but they're still working construction. It's vile, but it is what it is. (Not them, the companies are vile for what they're doing, the workers are simply surviving however they can)
I don't know the contract details but these workers are picked up at the facility every day with an 8-person van and brought to the job site. Not only will it be very difficult to get a rental apartment for 2 months at less than €600/month, you also miss out on the transportation if you do.
And these jobs are usually picking strawberries out in the rural sections or working for Amazon at some industrial estate that doesn't have public transit late at night.
