Bruised and battered, the Silver Ferns will be charged with adrenalin for their biggest game in four years tonight - the defense of their world netball title.

Their gripping semifinal fight-back win by 59 goals to 49 over Jamaica last night took its toll, but Ferns coach Ruth Aitken insisted they are prepared for the physical battle.

In the other semifinal match, Australia dispatched England by 51 goals to 33.

Since the last World Championships in Jamaica in 2003, where the Silver Ferns beat Australia in the final 49-47, the neighbors have met 18 times. The record stands at 10 victories to the Silver Ferns, eight to Australia.

The Silver Ferns/Australia final kicks off at 7:10pm tonight.
