Cronulla MP Mark Speakman has apologised for the axing of on-demand buses in Sutherland Shire, blaming a poor booking system and lack of promotion.
Transport for NSW announced in a statement on Tuesday the service would end on November 17.
"I apologise to Transdev on-demand bus service customers that I have not been successful in securing a further continuation of the trial," Mr Speakman said.
"The service appears to have been poorly patronised.
"I received numerous comments about the poor booking system and its high dropout rate. I can't help but think that this, plus poor promotion, were big contributors to insufficient patronage.
"However, I know that for many who use the service it overcame a lot of their serious transport difficulties and for many the termination of the service is distressing."
Mr Speakman suggested the possibility on-line buses could return with changes in the future.
"I don't want to raise hopes unrealistically, but when the local bus franchise comes up for retendering in about a year's time, I will urge that detailed consideration be given to procuring a new on-demand bus service as part of this," he said.
"Maybe a service with, say, more limited hours would be viable.
"If this is to happen, Transdev will have to lift its game."
Comment has been sought from Transdev.
