Westeros, like the Australian politics, is a world where "power was also pursued relentlessly," wrote ex-Prime Minister Julia Gillard.

As the fourth series of Game of Thrones debut in the United Kingdom, Ms Gillard compared her time as a Prime Minister of Australia to the fantasy series.

In an article she wrote for The Guardian, she shared that curiosity about a 'foreign' language spoken by her staff sparked her fondness for the Game of Thrones.

"The staff who worked with me most closely talked in a language I didn't understand, discussing the Wall and the White Walkers, the Iron Throne and dragonglass. During moments of rest, the police on my protection detail would be hunched over iPads watching and talking the same strange lingo."

She found herself addicted to the show after watching series one over three days when she was on leave in 2012. Already too much involved, she watched the following series as soon as she could.

She wrote that the aborted March 2013 coup was like barracking for the Khaleesi.

"After all, what girl has not yearned for a few dragons when in a tight spot?" she wrote.

Ms Gillard's reign as Australia's First Woman Prime Minister was made all the more 'colourful' by misogyny of some male politicians, but she had risen to the occasion. This, she saw too with the female characters in the series.

"In this world of constant war, female characters have never been relegated to the sidelines. They confound the stereotypes. Being a wife or being a whore does not mean being a bit player in a male drama. The women of combat command our attention once again."

When she was ousted from power, Ms Gillard said that her noblest takeaway and privilege was that after her, "it will be easier for the next woman and the woman after that and the woman after that" to become the prime minister.

Maybe, it is in the same way of thinking that she viewed the Game of Thrones being not just the story of Everyman but instead the story of would-be rulers.

"Instead, the lot of the everyman and everywoman forms only a backdrop to the story of would-be rulers and their clashes for power."

Ms Gillard's article was amusing in the same way that it offers a political perspective on a supposedly fantasy series.

And as the fourth series premiered, she said,"In Australia, winter is coming. What better way to spend its evenings than immersed in Game of Thrones?"
