There is 1 dedicated cruise ship that sails at he end of the West Australian season to Hull or Liverpool. Many others go to the UK but take various routes and do a lot of stopping off. By the way I live in Perth and if you want more information e-mail me at firstname.lastname@example.org Maurice Lamberth.
There are number of cruises ship over the period December to March that do world cruises and come back to the UK but you would have quite a few ports of call to visit before arriving back here in the UK and the time span could be a few weeks rather than a few days.
Round the world cruises may stop at Freo and then you can take her back to UK. Saga, Cunard and P&O spring to mind so check their sites; the ship the Lamberth is referring to is the Funchal I believe, an old tugboat that I have sat on the beach (Port Beach in Freo!) and have watched her sail out....
