The release of her self-titled album juliagrace on the Parachute Music label in October of that year scored four number one singles in New Zealand. The album received the Tui Award for Best Gospel/Christian Album at the New Zealand Music Awards in 2006. This Album was followed up by the album Beautiful Survivor.
