Google Maps API not centering the Marker

Question

I have Google Maps on a website that sets the marker based on an address.

Here's an example (click the location tab): http://www.weddinghouse.com.au/wedding-directory/zoning-in-personal-training/

As you can see there is no marker on the map. But if you scroll upwards the marker is sitting just out of view.

Is there something wrong with my code? The weird thing is very few addresses actually show correctly but the majority don't. Is there something wrong with my code or is it Google?

Here is my JavaScript Code:

<script type="text/javascript">
$(document).ready(function(){
    load('Zoning In Personal Training', '27 Sitella Drive, berwick, VIC, 3806');
});
</script>

-

function load(title, address, type) {
    if (GBrowserIsCompatible()) {
        var map;
        var geocoder;

        map_id = document.getElementById("map");
        map = new GMap2(map_id);
        map.addControl(new GSmallMapControl());
        map.setCenter(new GLatLng(24, 0), 17);
        map.enableDoubleClickZoom();

        if (type == 'sat') {
            map.setMapType(G_SATELLITE_MAP);
            map.addControl(new GHierarchicalMapTypeControl());
        } else {
            map.setMapType(G_NORMAL_MAP);
        }

        geocoder = new GClientGeocoder();
        geocoder.getLocations(address, function (response) {
            map.clearOverlays();
            if (!response || response.Status.code != 200) {
                //map_id.innerHTML('Could not find address on Google Maps');
            } else {
                place = response.Placemark[0];
                point = new GLatLng(place.Point.coordinates[1], place.Point.coordinates[0]);

                map.setCenter(point, 17);

                // Create our "tiny" marker icon
                var icon = new GIcon();
                icon.image = "http://labs.google.com/ridefinder/images/mm_20_red.png";
                icon.shadow = "http://labs.google.com/ridefinder/images/mm_20_shadow.png";
                icon.iconSize = new GSize(12, 20);
                icon.shadowSize = new GSize(22, 20);
                icon.iconAnchor = new GPoint(6, 20);
                icon.infoWindowAnchor = new GPoint(5, 1);

                // Creates one of our tiny markers at the given point
                function createMarker(point, index) {
                  var marker = new GMarker(point, icon);
                  var myMarkerContent = "<div style=\"width:200px; overflow:auto;\"><strong>" + title + "</strong><br />" + address + "</div>";
                  map.addOverlay(marker);
                  marker.openInfoWindowHtml(myMarkerContent);
                  GEvent.addListener(marker,"click",function() {
                     marker.openInfoWindowHtml(myMarkerContent);
                   });
                }
                createMarker(point);
            }
        });
    }
}
