She defeated home player Bec Van Asch 7-6, 2-8, 5-0 today at the Warilla club in New South Wales to win the world title.
Beere had beaten Jo Edwards (New Zealand) in the semi-final the previous day in a repeat of last year's final, which Edwards had won.
The Guernsey star previously won the World Indoor Under 25 Pairs Championships in 2008 with David Axon from Wales, a silver medal last year at the World Cup, a silver medal at the World Champion of Champions in 2009 and a bronze at the 2015 Atlantic championships, plus two silvers and one bronze at the last two European Championships.
She will be staying in Australia for the Commonwealth Games and will be enjoying a few days rest before some practice at the Warilla Club before heading to the Gold Coast greens.
'Lucy played really well all week, we are all so very pleased she went one better than last year and won the Gold.
'I know many local bowlers stayed up and watched online the final which finished at around 4am this morning, again more world success on the bowling green,' said a very pleased Garry Collins, Bowls Guernsey events coordinator.
