The line for the bus to Central Station has long irritated students at UNSW in Kensington, Sydney. But construction and service changes linked to the eastern suburbs light rail project have taken things to a whole new level, students say.

The new university year has seen daily queues stretching hundreds of metres from the bus stop on High Street into the university quadrangle each afternoon.

A survey of students last week found the average wait to just get onto a bus was between 30 minutes and an hour.

Student representatives are collecting signatures in order to present a petition to NSW parliament.
