Suggest me a digital camera pricing around Au$500?

I don't care about the camera type whether SLR, Mirror-less, point and shoot, No compromise with image quality. I don't want to pay anymore. Brands preferred is NIkon, Canon and Sony. I don't care about the zoom. But Manual control over the camera is highly preferred. I love macro shoots. Aperture proirity!

Nikon D3100 or Canon Rebel T3.
