I guess I might be able to help you find cheap houses in Melbourne.
I have found houses for $285 per week.
These belong to student apartments, nothing too special, just average. They have studios, two-bedroom, three-bedroom, and four-bedroom options.
The $285 one is a four-bedroom type.
The private space is your own bedroom, which comes with a bed, desk, chair, and wardrobe.
Bills are included, and it's a 5-minute walk to the University of Melbourne and RMIT.
Not only this layout, but other layouts are also available for just a little over $300.
