The adventurers were delayed from the further pursuit of their ambition by ship's duties. The Reliance was ordered to convey to Norfolk Island an officer of the New South Wales Corps required for duty there, as well as the Judge Advocate. She sailed in January, 1796. After her return in March, Bass and Flinders, being free again, lost no time in fitting out for a second cruise. Their object this time was to search for a large river, said to fall into the sea to the south of Botany Bay, which was not marked on Cook's chart.
