Filling a very large pond

Hi, have read a few other articles dating back a while and just wanted to make sure I'm doing the right thing. Garden novice!
I had a large pond in my garden, 2m wide, 3m in length, and .75m in depth. I have drained all the water, removed rubber layer, as well as the carpet and underlay underneath that.
Now I need to fill it. From what I have read, and what I intend to do, break/loosen floor/ walls of pond using a fork to aid drainage. Then large hardcore/ rubble until about 6-12 inches remain. Then fill with topsoil. Expect some drop as the topsoil over the year, but fill as needed?
Any help and guidance is appreciated
Thanks

    Why have you drained it and removed the liner?
    Based in Sussex, I garden to encourage as many birds to my garden as possible.

    Sorry, should have been more specific, bought a house with the pond in it, we don't want it what with dogs/ kids and so want to fill it and turf it

    I would have a minimum of 12 inches of soil to avoid the ground drying out too quickly in the event of having hot weather.  Also expect the ground level to drop a surprising amount as the soil settles into the voids in the hardcore fill.  I have a couple of raised beds and the levels in those dropped at lest 6 inches in the years after construction.  The drop may be less if you firm the topsoil as you fill.  I'd suggest walking on it after about every 3 inches of topsoil fill.

    Thanks for the reply. Reassuring it seems I'm on the right lines. Have read this is the case, and needs topping up over the years
