Twenty new-look county councils would be created to cover regional areas and councils in the lower Hunter Valley and central coast would be merged, under sweeping changes proposed by the Independent Local Government Review Panel.

In a new report, the panel has proposed a new "global city" of Sydney, from the central business district east to the coast and south to Botany Bay.
