Using a mixture of humour and smarts, the student debaters successfully argued their point that the generation gap does not exist.

David Goss from the University of the Third Age (Northern Suburbs branch) debate team, conceded the better team won Wednesday's debate at Thirroul Library.

"I thought they actually won the debate by being a little bit more coherent than we were, or consistent in their arguments," Mr Goss said.

The one-time diplomat for the Department of Foreign Affairs and Trade enjoyed the debate but felt the generation gap was in fact greater.

"I think it's a good thing to cross the generation gap, whether it is greater or not," he said.

"I think the gap is greater but the bridges across it and the love between the generations always manage to link it."

Bulli student Lani Taylor was named best debater by adjudicator Wollongong Lord Mayor Gordon Bradbery.

The year 8 student had the audience in stitches at one stage when she said "without the advancement of technology many of you [opponents] wouldn't be here today".

"I really enjoyed the debate," Lani told the Mercury afterwards.

"I hope we can do it again soon." 

Bulli High School principal Christine Gregory said everyone had a really good experience and enjoyed learning from each other.

"The generation gap, whether it is widening or shortening, what was evident today was the use of humour, and I think both sides had a little bit of healthy banter respectful of each other," Mrs Gregory said.

"I think people in the audience appreciated the humour from both sides. I know I appreciated it."

The principal added the result showed how one should never underestimate the power of young people.

"They are articulate, they're learned, they're respectful and young people have a lot to offer society," Mrs Gregory said.
