He has made it no secret he has a soft spot for the Australian treat Tim Tams.

And Torchwood star John Barrowman was overwhelmed with packets of the chocolate biscuit after fans gifted him the moreish snack at the annual Oz Comic-Con event in Melbourne on Saturday.

The Scottish-born American star received so many, he started playing the block-stacking game, Jenga, with the various varieties.

The former Doctor Who star was so surprised by the goodness of his Australian fans, he took to twitter to show off his never-ending supply.

In one tweet, the 49-year-old actor is seen pointing to a wall of Tim Tam's which included four layers, along with two Choclicious packets.

He wrote alongside the picture: 'Keep the Tim Tams [sic] coming.'

In another tweet, the triple threat is seen leaning over a 'Tim Tam' pillar.

He captioned the post: 'It's a TimTam Tower! Oz Comic-Con.'

In another upload to social media, the causally cut TV star is pictured next to a giant tower of chocolate biscuits.

'The Tim Tam Tower is growing... Oz Comic Con,' he said in the post. 

The causally clad star, who donned a black printed T-shirt, looked to be in high spirits as he signed autographs and posed with adoring fans at the pop culture event.

Meanwhile, John has revealed he would like to reprise his role as Captain Jack Harkness in Doctor Who and has teased he is heading to Cardiff, Wales, where the sci-fi drama is filmed for a secret project.

Speaking on BBC's The One Show about a possible comeback, he said: 'I'd love to, keep watching. Keep watching, I've love to! I don't know! It's not up to me ... but keep watching!'

John made his first appearance in Doctor Who in 2005, and then in spin-off show Torchwood, and continued to make cameos in both programmes until 2013.

Speaking about his next project, he said: 'I will be back in Cardiff in about a week and a half ... but I'm not telling you what for!'
