Carlos Checa can call himself the proud owner of a new lap record around the Phillip Island circuit as he blitzed his rivals during the third of four World Superbike test sessions.

Though his lap won't be recorded officially, his effort of 1min 30.578secs - set just before the chequered flag was dropped - is almost half a second faster than Regis Laconi's benchmark time from 2009.

Prior to that, Checa had been challenged by Sylvain Guintoli and Jonathan Rea, but the Spaniard's final effort was enough to place him six tenths clear of the second and third placed pair.

Another impressive session for newcomers Effenbert-Liberty Ducati, Jakub Smrz backed up team-mate Guintoli in fourth place - albeit half a second slower than the Frenchman - while Joan Lascorz, who holds the fastest lap at Phillip Island at Supersport level, was a fine fifth quickest on the new Kawasaki.

Michel Fabrizio and Marco Melandri lifted Suzuki and Yamaha into the mix in sixth and seventh, while Eugene Laverty, Tom Sykes and Noriyuki Haga rounded out the top ten, the latter making a significant improvement on his Monday effort.

Elsewhere, Max Biaggi was a modest 11th, though at least he ventured onto track, unlike team-mate Leon Camier, who is sat on the sidelines as he recovers from illness.

Further back, it was a tough session for BMW, with Leon Haslam falling twice on the way to 14th, though he did still set a faster time than counterparts Troy Corser, James Toseland and Ayrton Badovini, who filled positions 15th through 17th.
