The mother of a NSW high school student who took his life after merciless bullying and beatings at school has made a heartfelt appeal for the inquest into his death to "make a difference".

Deputy NSW Coroner Malcolm MacPherson adjourned the inquest on Friday after a fortnight of taking evidence into the death of 14-year-old Alex Wildman on July 25, 2008.

His sobbing mother, Justine Kelly, told the inquest moments before hearings came to an end that her son would have turned 16 next Tuesday.

"I would have been attending the RTA to get his Ls but instead I'm sitting here in a court and wondering why he's dead," she told Mr MacPherson in a voluntary statement.

Ms Kelly told the coroner she hoped school bullies had learnt a lesson from her son's death.

"I hope they have genuine remorse and genuine regard for the life of my son," she cried.

"There are parents sitting here in court who can turn and look at their children.

"I have three children remaining, but I can never turn and look at my fourth again. All I have are photographs.

"He was a beautiful child. He didn't deserve the treatment he received.

"He didn't deserve it."

Two framed montages of photos of Alex have been displayed in the front of the small courtroom in Ballina each day of the inquest.

Each bears the inscription: "No child deserves to live in fear."

The coroner praised Ms Kelly and her husband Bill for their courage during the inquest.

"These proceedings have been tough, especially for Justine and Bill," he said.

"They have conducted themselves stoically and quietly with the utmost dignity."

The inquest heard Alex, who attended Kadina High School in Lismore, took his life after intense bullying by peers - much of it on social networking sites on the internet.

Counsel assisting the coroner, Peter Hamill SC, described Alex as a "highly intelligent and sensitive young man" who had been bullied at Sydney schools before moving to live with his mother and stepfather in Lismore to escape the torment.

"Nasty things, hurtful things were being said about Alex over the internet, and these things can best be described in the parlance of these times as cyber-bullying," Mr Hamill told the inquest.

Outside court, family solicitor Vince Boss said the inquest had shown there were a lot of unresolved issues.

The family hoped it would lead to improved policies and procedures at schools to deal with bullying, he said.

"(We hope) there should be enough information there for the coroner to be able to make some recommendations that will be worthwhile, not only for the public school system but also the private school system so we can ensure the situation in which Bill and Justine found themselves in with Alex won't happen again," Mr Boss said.

Mr MacPherson adjourned the inquest until December 11, with written submissions expected from the counsel assisting and other parties involved in the inquest.

He said his recommendations would most likely be handed down early in February 2010.
