Community Services Minister Gabrielle Upton announced on Thursday the signing of $8.6 million in contracts for a number of inner-city "outreach" services for the homeless.

Ms Upton first announced that funding in June,  reversing a controversial decision to move homelessness funding away from services in inner Sydney.

However, a number of specialist homeless charities, such as those catering solely for women leaving domestic violence or sexual abuse - many of which had been running for decades - were denied bids for the funding, which was  earmarked for larger and more general services.

"They were [vital] women-only services and they were facing extinction," said Roxanne McMurray, from SOS Women's Services. "This would have wiped them out".

Five inner-city women's services, some of which have run for more than three decades, were expected to close their doors and lose the use of their buildings in June.

After holding consultations, the minister confirmed on Thursday about $2 million in funding had been secured for the five threatened organisations. The programs include the Young People's Refuge, a program in the inner west for homeless girls aged 13 to 17 who have left domestic violence and sexual abuse.

"It was the last of its kind [in NSW]," Ms McMurray said. "We're absolutely elated that the Minister has supported [them]".

Ms Upton said: "Over the next three years, the NSW government will invest a record half a billion dollars right across NSW to tackle homelessness."
