McGrath's bowling was not of express pace.
Rather, he relied on unerring accuracy and subtle seam movement, which he derived from his high wrist action and lengthy follow-through.
 His height (195 cm), combined with a high arm action, allowed him to extract extra bounce, which often surprised batsmen.
In the later years of his career he developed as a swing bowler.

His uncomplicated method and natural physical fitness were significant factors in the longevity of McGrath's career.
In 2004, he became the first Australian fast bowler to play 100 Tests.
In the first innings of the ICC Super Series Test match in 2005, McGrath passed Courtney Walsh to become the greatest wicket-taker among fast bowlers in Test history.

McGrath was regarded as one of the best fast bowlers in the world and has had success against every opposition team, in both Test and one-day cricket.
He deliberately (and publicly) targeted the opposition's best batsmen prior to a series in an attempt to distract them, a ploy that regularly worked.
At the beginning of the Frank Worrell series against the West Indies he stated in interviews before the match that he would dismiss Sherwin Campbell for his 299th wicket, then remove star batsman Brian Lara for his 300th wicket the very next ball.
This happened as planned, and he followed this with the dismissal of captain Jimmy Adams to complete a memorable hat-trick.
The targeting of opposition batsmen was generally successful; he dismissed Mike Atherton of England 19 times – the most times any batsman has been dismissed by one bowler in cricket history.
On the other hand, he targeted Michael Vaughan prior to the 2002/03 Ashes series in Australia, with Vaughan going on to score three centuries at an average greater than 60.
He targeted Andrew Strauss in the 2005 series in England, who went on to score two centuries.

He also tended to engage in sledging of opposition batsmen and teams, though it didn't always pay off.
Before the 2005 Ashes series he predicted a 5–0 whitewash for Australia, and even said that if England won the Ashes he would return to Australia by boat, but England prevailed 2–1.
However, this did not dissuade him from making a similar 5–0 prediction for the next Ashes series, in Australia in 2006/07, which turned out to be true.
He finished his career as the most successful Test fast bowler and third-highest Test wicket taker.
