Public interest in Oscar Pistorius's trial seems to have waned a bit with fewer people queuing up outside courtroom GD in the High Court in Pretoria on Wednesday morning.

When Pistorius again took the stand on Tuesday, scores of people had arrived at the court, hoping to be in the gallery for the proceedings.

While the back bench, which is reserved for the public, was full on Wednesday, people sat comfortably with space left over for more people.

Pistorius arrived in court dressed in a black suit and sat in the dock with his head bowed.

He later spoke to members of his legal team and stood up to talk to his family two benches behind him.

The paralympic athlete is charged with murdering his girlfriend Reeva Steenkamp on February 14 last year.

He shot her through a locked bathroom door in his Pretoria townhouse. He claims he mistook her for an intruder.

However, the State argues that Pistorius intentionally shot her following an argument.

Pistorius is also charged with three contraventions of the Firearms Control Act, one of illegal possession of ammunition and two of discharging a firearm in public.

He has also denied guilt on these charges.
