According to Wellsworthstation (SiF), while reading a new issue for the May Thomas & Friends Australian magazine edition, an advertisement was found.
It said "Watch 'Day Of The Diesels' at Hoyts Cinemas at 10am, Saturday and Sunday mornings from July 23".
This move may surprise Aussie Thomas fans who get to see the newest special before the UK and particularly the US as of now.
It is not currently known as to why Australia will see it first as no links can currently be found, even on the Hoyts Cinemas website. It is still possible that the US could see the special around the same time, as Misty Island Rescue premiered around that time last year.
The move could also apply to New Zealand while it was revealed back in early February by cast member Ben Small that the special had wrapped production on it's animation, then later, it's voices.
Day of the Diesels premieres in Australia starting from July 23rd 2011 at Hoyts Cinemas on Saturday and Sunday mornings, 10am while the special will currently reach the UK & US in September.
Thanks to Wellsworthstation for the alert.
