Simon,
 
If by Black-tailed Gull we are referring to Larus crassirostris, then not only is it in the same family (Laridae) as the Silver Gull Larus novaehollandiae, but it is in the same genus (Larus). So, sorry but you have your wires crossed in suggesting they are in different families. They don't look that much different in shape either and I suspect just by a quick look at Geoffrey's, picture and description that it is probably not a Silver Gull.
