[citation needed] Brady was convicted of stealing a basket, some butter, bacon, sugar, and rice, and tried at Lancaster on 17 April 1820.

[4] On 7 June 1824, Brady was part of a group of fifteen escapees from Sarah Island who sailed a whaleboat around the south coast to the River Derwent and spent the next two years as bushrangers.

Governor George Arthur posted rewards for the capture of Brady and his gang of 25 pounds sterling and a conditional pardon.

I also caution John Priest that I will hang him for his ill-treatment of Mrs. Blackwell at Newtown.In November 1825, a description of the Brady's gang of bushrangers was published, provided by Mr. R. Denne, overseer for Silas Gatehouse near Grindstone Bay (100 kilometres (60 mi) north-east of Hobart).

He described his captors as having no fixed leader, "though the opinions of Brady or Dunne are generally listened to", adding that "they frequently debate and quarrel for hours together, about their future proceedings".

On 28 March 1826, in consequence of private information, Lieutenant Williams of the 57th Regiment with 14 soldiers and four armed prisoners made contact with Brady's gang south of Launceston.

News quickly spread that Brady was caught and the townsfolk turned out to see the captured felon pass by on horseback.

There were multiple unsuccessful petitions to halt his execution, and his cell was filled with wine, fruit, cakes, confectionary, and flowers from the ladies of Hobart Town.

[2] The Herald wrote of his death:[2] There was a hush, broken only by stifled sobs, as the bushranger knelt to receive the last consolations of his faith.

Then, standing erect, he bade adieu to the multitude and died more like a martyr than a convicted felon.One of his hideouts is now known as Brady's Lookout and is a popular picnic area with views over the Tamar River.

[12] There is also another of his hide outs at Notley Hills Gorge, with a lovely bush walk, and an information board about Brady.
