Hi honey. Welcome to Melbourne. That's an absolutely massive area to look in. I'd probably narrow down where you want to live first, then pick the best school in that area. Also you will need to consider public vs private schools (private schools in Melbourne can be very expensive).

What are your other housing priorities? Close to a train line? Close to the beach? Will DH be driving to work and if so, where is work and how long does he want to spend in the car? What other sort of amenities do you want - do you need space for a dog to roam, close to a park or shopping centre etc?

Once you've worked out those details and narrowed down an area, it will be much easier to help with schools

Best wishes.
