The CEO of Dublin-based homeless charity Inner City Helping Homeless has called on the Government to establish a fully equipped dedicated Housing Agency to tackle the problem of homelessness.
Anthony Flynn said there have been 29 failed government initiatives and there is still no realistic end date on homelessness.
He said too many ministers have passed through the Department of Housing over the past number of years.
He added he did not believe that agencies, like the Dublin Regional Homelessness Executive, had the resources they need.
Speaking on RTÉ's Morning Ireland, Mr Flynn said there are currently over 3,000 children in emergency accommodation, and it is feared that there may be more children than adults using homelessness services by the end of the year.
He said that putting a face to the situation was a priority.
With this in mind, the group launched its #MyName campaign.
In a statement, the Department of Housing, Planning and Local Government said "Minister for Housing Eoghan Murphy acknowledges that the current level of homelessness, which families and individuals are experiencing at present across the country, is totally unacceptable.
"People can be assured that this issue remains the top priority for Government at present.
"Resources and funding are not an issue and will not be an obstacle to the urgent delivery and heavy lifting that is now required."
It continued: "The minister has written to local authorities requesting that they urgently intensify their efforts and ramp up social housing activity and delivery on the ground.
"In addition, next week the minister will hold a Housing Summit in the Custom House, so that he, each of the 31 local authorities' chief executives and the department's senior management housing team can explore and finalise solutions that will help to house those families and individuals in emergency accommodation and manage more effectively the influx of new households finding themselves homeless."
Meanwhile, Minister for Foreign Affairs Simon Coveney, who preceded Mr Murphy in the housing role, said the homelessness crisis remains a huge priority for the Government.
Speaking on Morning Ireland, he said the Government needs to focus on multiple approaches in order to bring the problem under control.
Mr Coveney said more people were taken out of homelessness than ever before last year, but there are still far too many homeless people.
