There are snags on the barbecue and one attendant tells SBS News the Homelessness Week event — dubbed Refresh, Recharge & Shine — is "fantastic"."There should be more things like this for people in need," Marie said while assisting at the event.NSW housing and homelessness minister Rose Jackson, who was also there on 3 August, told SBS News she believes "people don't like to think about what it's like to be homeless" but that it was important to draw the issue into the national conversation."Knowing how many people are living homeless, where they are, what their demographic is, their age, their gender — that's critical information for the government."Jackson said data collected during the Census of Population and Housing on 11 August will be "crucial" for allocating resources and services to people experiencing homelessness.But collecting this information can present logistical challenges She said the Census provides "precious evidence", but believes it can be challenging to capture accurate data on homelessness, particularly in vast urban areas or in regional and rural Australia
