More than 5,000 students are expected to take part in a major demonstration in the city today.
The Union of Students in Ireland (USI) is organising the event to call for publicly funded higher level education.
The body represents nearly 400,000 students across the country. It wants greater investment in the area.
USI President Michael Kerrigan says the demonstration aims to send a strong message to the Government.
"We're well aware that there's no bottomless pit, this is something we're not asking for.
"It's something we're looking for over time between now and 2030 - that the student contribution fee is reduced.
"Since 2008 it has risen 375% - there's no fee in the country that has gone up that much in the last decade.
"We're looking for it to be reduced to the same rate that it was increased, and to have publicly-funded education by 2030".
