Patrick began working fulltime as an author in 2001, after a long career as a journalist and television presenter.  He's established himself as one of Australia’s leading non-fiction authors, broadcasters, filmmakers and public speakers.

In 2002 he published The Spirit of Kokoda (Hardie Grant), the story of the battles which saved Australia in WWII.  It stayed on the national best-seller list for nine weeks.  Patrick followed it with It’s Never Too Late (Hardie Grant), a best-selling motivational book which has now expanded into a seven-book series. 

Patrick’s third book, The Spirit of The Digger (Macmillan), the essence of the Australian soldier told through the words and actions of the Diggers themselves, was launched in 2003, ended the year as Australia’s top-selling history book, and continues to sell strongly. 

His fourth book, Back from the Dead (Random House), the story of the 2002 Bali bombings told through the eyes of Peter Hughes, the face of the tragedy, was published in late 2003.  It stayed on the best-seller list for eight weeks. 

Happiness and The Essence of Kokoda, a concise guide to the Kokoda story, (Hardie Grant Books) were released in 2005. 

The Spirit of Gallipoli and Balance, It’s Never Too Late (both Hardie Grant) hit the shops in April 2006.

Next Patrick wrote biographies of former triathlon champion Greg Welch Heart of a Champion … the Greg Welch Story (Murdoch Books) and former Chief of Defence Force, General Peter Cosgrove,  Cosgrove … Portrait of a Leader (Random House).  The latter reached Number Four on the Best-Sellers List.

Patrick's best-selling book, Fromelles, (Hardie Grant) the story of the quest to find the missing Diggers from the WWI battle fought at the tiny French village in 1916, was published in November 2007.

An updated and expanded paperback edition hit the shelves in the first week of November 2008.  The new edition brought the story full circle, covering the archaeological dig at Pheasant Wood which confirmed, at last, the final resting place of 250 missing Diggers buried by the Germans after the battle.  The remains of these men were exhumed in the French summer of 2009 and were given a long-awaited individual re-burial in July 2010 in a newly-constructed cemetery near the village of Fromelles.

(An abridged and updated version of the work, titled, Our Darkest Day, was published by Hardie Grant Books in August 2011.)

In March 2009, Patrick published Now Is The Time, in his inspirational series.  Now Is The Time is a collection of reminders that within us lies power to change our lives - for the simpler and for the better - by embracing the moment and seizing the day. Now Is The Time was published simultaneously in Australia and the U.S.
