I am using a couple of redirector pages to direct people from top level links to sublinks. I assume this is what they are used for!

Anyway, they seem to work fine viewed in the browser when I am logged in. The links appear in my top menus and when clicked on, they correctly redirect to the sub-level link. However, when I am not logged in, these redirection links do not appear at all. I checked that the box for 'show in menus' is ticked for these redirector pages, re-saved and re-published the pages and added the ?flush=1 query string - still same thing.

Any help would be much appreciated.

I also use redirector pages like this (very useful!) but I haven't seen the issue you describe.

Maybe flush your browser cache too. Other than that, you don't have something in your template that hides that section if you're logged in?
