The Gladiator star has two children - Charlie, six, and four year old Tennyson - with his wife of seven years, Danielle Spencer.
And the doting dad decided to make good use of his time while singer Spencer is in a two-week stint of rehearsals, by heading out into the bush with his boys.
In a post on his Twitter.com blog, Crowe writes, ""Her indoors has rehearsal every day for the next two weeks, so the boys and I are going on our first Road Trip. 600 kms (kilometres) into the bush. Cool. The wife thinks I'm bonkers (mad), but I love driving long distances.""
