Depending on how many people get involved, you might be able to get away with playing at someone's house. One large table ought to be enough for 4 players -- assuming of course you have a large table that can be dedicated for an extended period of time! Similarly two smaller tables might be sufficient.
If you need more space than is available at a "typical" house, then you're going to need to investigate public venues. Public libraries usually have meeting rooms, the question is cost/availability. Similarly for neighbourhood meeting halls. Scout halls and RSL venues can also be an option. You just need somewhere relatively accessible to everyone, which in the Newcastle area, ought not to be that hard.
The most important thing, though, is getting those lines of communication going amongst yourselves. Somebody needs to volunteer to be a central co-ordination point, and that someone needs to get everyone's email addresses and confirm that everyone is responding. If someone reaches out and gets ignored, the whole thing will just fall apart.
