The French described it as a "monument to drivel", the Italians decried it as "old-fashioned", and the Portuguese used their 1974 entry as the signal for a military coup. Yet despite (or perhaps because of) these facts, Australia loves Eurovision.

And one Australian in particular loves Eurovision – Katharine Murphy, deputy political editor of Guardian Australia. She'll be live blogging the SBS broadcast on Sunday which starts at 7.30pm EST especially for Australian readers. Well, it makes a change from live blogging parliament – though it may not be much more melodious.

As in parliament, before you join her on Sunday, we must raise a couple of points of order. Most importantly, this year the Guardian is actually live blogging Eurovision twice. The first live blog will be from London and cover the live broadcast which take places on Saturday night in Copenhagen around 4am EST. So although it will undoubtedly have great gags, courtesy of live blog master Stuart Heritage, if you want to avoid knowing who wins it might be a good idea not to read it until after the show has been broadcast in Australia. We'll endeavour to keep all spoilers off the Guardian Australia homepage too.

Other than that, no holds are barred. So as well as tweeting, waving the European flag and drinking unpleasant liqueurs from participating nations, please add your thoughts to Katharine's live blog. It won't be Eurovision without you.

And between now and Sunday, why not catch up with our coverage so far? We've got a beginner's guide to Eurovision, an interview with the host Pilou Asbæk (formerly of Borgen), an eye-popping gallery of the best Eurovision outfits of all time and a rundown of the controversy over Austria's contestant, the brilliantly named Conchita Wurst. See you on Sunday.
