On 2 June 1842, George McGrath was killed by his Aboriginal guides at Bonney’s Well while travelling to Portland. Wira Mildara and Wek Weki were arrested for the crime in 1845 and tried before the Supreme Court. Both found guilty, but Wira Maldira was executed on the grounds that he ‘knew our habits and some of our laws’ ans was judged more culpable.
