With his fiery approach to opposing batsmen and a desire to bowl all day, Siddle can rightly be considered the latest uncompromising Aussie seamer to follow in the footsteps of the likes of Craig McDermott and Merv Hughes.
Although not intimidating in either size or stature, the 24-year-old from Victoria is not to be underestimated by opponents.
His willingness to run through a brick wall for his country has seen him quickly become a hero with the fans, though his 29 wickets in seven Tests show he's more than just an honest grafter.
Injuries hampered his progress at the start of his career, including dislocating his shoulder soon after undergoing reconstructive surgery.
However, Siddle fought back to become a consistent wicket-taker for his state side that eventually resulted in an international call-up.
The right-armer made his Test debut in India - not exactly an easy beginning for a seamer - and gave an early warning to the hosts by hitting Gautam Gambhir on the head with his very first delivery.
Overlooked for the rest of the series in the sub-continent, Siddle was drafted back into the side to face the South Africans on home soil.
Although he couldn't prevent the Proteas winning 2-1, he helped the Australians gain instant revenge in the return series, taking 11 wickets in the wins in Johannesburg and Durban.
