Paul Goodison, a favourite from Great Britain, was in fifth place and recently crowned ISAF Rolex World Sailor of the Year Tom Slingsby (AUS) was 13th.
The morning Laser fleet also included some of the participants in the Perth 2011 Emerging Nations Programme which is designed to assist developing sailing nations to participate in the Olympic Sailing Competition.
Peter Cook from the Cook Islands said his aim was to qualify for the Perth 2011 ISAF Sailing World Championships. "Australia is a great place to sail," Cook said. "With the ENP program just finished two weeks ago, this regatta is a build up to Perth 2011 - it's great".
In the afternoon, the Laser Radial competition started with Fremantle's famed sea breeze fully in for the two races. Two young local sailors from Australia, Matthew Wearn and Tristan Brown, lead overall.
The final results of the two races for the Ladies provided success for Alison Young (GBR) taking the lead on day one, followed by world number seven, Nathalie Brugger (SUI). Tuula Tenkanen from Finland is third.
The highlight of the afternoon was the clash of the titans in the Finn class, with interest centred on the return of Ben Ainslie (GBR) to a full time Finn campaign for the London 2012 Olympic Games.
ISAF World number three, Jonathan Lobert (FRA), took the first day's lead, followed by Daniel Birgmark (SWE) in second place and Rafa Trujillo Villar (ESP) in third.
British sailors put in a solid performance with Andrew Mills fourth, Giles Scott fifth and Ben Ainslie in sixth place.
Wednesday is set to be a thrilling day with all four race courses operating.
