I'm very new to OpenLayers and I'm trying to show a map on my home page, which shows only Australia, and then later add some points on the map. The important thing right now, is to just open the map to Australia.

I'm using the example found on OpenLayers home page, with:

```
var map = new OpenLayers.Map('map');
var wms = new OpenLayers.Layer.WMS( "OpenLayers WMS",
        "http://vmap0.tiles.osgeo.org/wms/vmap0", {layers: 'basic'} );
....

```

I'm guessing that I have to pass something to the constructor to have it display only a specific region?

Thanks,

Sam
