“I had a couple of tears, which is fantastic. That’s always the best thing about Doctor Who,” said one Whovian.

“I can’t really pick out a favourite part; it was fantastic all the way through,” said another fan.

The Day of the Doctor featured doctors past and present.

It also marked the final episode for Doctor Matt Smith and the first appearance of a new Time Lord, Peter Capaldi.

“That was my favourite part of the episode. I mean I’m a big David Tennant fan and to see all three together – the charisma between the three of them was amazing,” said a fan.

“I thought it was actually a really well done, clever way of celebrating 50 years,” said another.

Australia has strong connections with the long-running science fiction series, which was first broadcast on the ABC in 1965.
