I have managed to crack it using a custom ModelBinder. I create a basic class called QueryString

    public class QueryString
    {
            private readonly IDictionary _pairs;

            public QueryString()
            {
                    _pairs = new Dictionary();
            }

            public void Add(string key, string value)
            {
                    _pairs.Add(key.ToUpper(), value);
            }

            public string Get(string key)
            {
                    return _pairs[key.ToUpper()];
            }

            public bool Contains(string key)
            {
                    return _pairs.ContainsKey(key.ToUpper());
            }
    }

Then I create my custom binder for that:-

    public class QueryStringModelBinder : IModelBinder
    {
            public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
            {
                    var queryString = new QueryString();
                    var keys = controllerContext.HttpContext.Request.QueryString.AllKeys;

                    foreach (var key in keys)
                    {
                            queryString.Add(key, controllerContext.HttpContext.Request.QueryString[key]);
                    }

                    return queryString;
            }
    }

In my Global.asax I register it:-

ModelBinders.Binders.Add(typeof(QueryString), new QueryStringModelBinder());

Now I can use that in my RedirectController:-

public RedirectToRouteResult Item(QueryString queryString)
{
    // user QueryString object to get what I need
    // e.g. queryString.Get("action");
}
