What's the point though?
If the aim is to grow the comp to new markets, new fans, new players, then PNG, WA, or NZ2 are the logical options.
Central Coast or another SE Queensland team doesn't bring in new fans, it just cannibalises existing fans from other clubs.
So what you are telling the people and the juniors ( who are involved in very large comps )
Sorry you can't have a team of your own you will just have to pick one of the existing Sydney clubs and support them !
After all just look at the western half of Sydney which certainly needs
Parramatta ,Canterbury , Wests Tigers and Penrith and if you prefer
Manly ,Eastern suburbs ,St George Illawarra or Cronulla or Souths .
I'm sure Central Coast people would not wish to support Qld ,Melbourne and definitely not
Newcastle which has its own large area and of course NZ
Most of the CC pop were born there.
They were allowed to have a soccer team which in the last year and it turned out to be the most successful team in Asia !
Its feedstream of juniors would be enormous .The infrastructure is already there !
The fact that Manly dudded Nth Sydney all those years ago is not the fault of the Central Coast
