At an emotional press conference in Batemans Bay, member for Bega Andrew Constance came out swinging against the Red Cross, Salvation Army and St Vincent De Paul for taking too long to distribute money.

"The money is needed now, not sitting in a Red Cross bank account earning interest so they can map out their next three years and do their marketing," Mr Constance said.

"We need a very real change, very quickly so that the money can get to those who need it most … people are on their knees and we can't have a drip-feed."

The Australian Red Cross has received $95 million to date and on Wednesday announced it had allocated $30 million to victims.

A spokesperson said the organisation has paid out 559 grants but has 1492 open applications.

St Vincent De Paul has raised $12.5 million and spent close to $1.1 million through financial packages for eligible households.

Since the Salvation Army's bushfire appeal began in November, $43 million has been pledged and $11 million has been received.

From September to January 23, $7.6 million worth of goods and cash relief had been distributed.

In the past two months, people all over the world have donated generously to charity appeals, the NSW Rural Fire Service, Celeste Barber's Facebook fund-raiser and animal rescue organisations such as the RSPCA.

Mr Constance, the NSW Minister for Transport and Roads, said it was "gutting" to learn only a third of the money donated to the Red Cross had been distributed when there were people who could not afford basics.

He said he had met people who were so traumatised they could not even leave their properties to register for relief.

The Minister, who has admitted he will need trauma counselling, issued a challenge to the managing directors of the three charities to come and see how people were living.

"Meet me in Batemans Bay at 8am on Saturday and I'll drive you the 300 kilometres of devastation on the far south coast.

"I'll show you the people, you can look them in their eyes and you can see their despair and the destruction that this firebomb brought to our region.

"They better turn up, they better have the guts to show up and be with me … I'll show them communities which haven't been on the map, like Kiah, like Nerrigundah, like the back of Bemboka, like Cooma."

The CEOs of St Vincent De Paul NSW and Canberra, Jack De Groot and Barnie van Wyk, have accepted Mr Constance's invitation.

The charity said over the past three days Mr van Wyk had overseen the distribution of $200,000 in financial relief to bushfire-affected locals on the south coast.

Over the new year period, areas of the south coast were completely wiped out by bushfires, with devastating losses in Batemans Bay, Conjola Park, Conjola, Cobargo and Mogo.

'Keen to get the money out': Red Cross

Red Cross director of Australian services Noel Clement said there was an absolute commitment to getting money in victims' pockets.

"We are keen to get the money out but we also need to make sure it's getting where it's needed," he said.

Mr Clements admitted some people were waiting weeks for relief money as there were challenges in proving where they lived after losing everything.

"We must manage the money so we aren't scammed … we want to make sure we are protecting donors' funds," he said.

He emphasised that recovery was a "long-term process" and it would take six months for some people to make claims or decide whether to rebuild.

In a statement, the Red Cross said chief executive Judy Slatyer had been on the NSW south coast last week meeting residents and had made "several attempts" to contact Mr Constance.

A spokesperson for the Salvation Army said its emergency relief was being distributed at evacuation and relief centres in bushfire zones.

"We understand relief can never happen fast enough for people in these traumatic circumstances. We are working as fast as we can," they said.

Former emergency service commissioner Peter Dunn is a Conjola local helping to lead the community's recovery efforts. He said donations had been "overwhelming" but long-term management was vital.

"I saw this in the Canberra [bushfires] in 2003 … there is enormous generosity when people are seeing images and hearing the stories on the media," he said.

"But after three to six months, other events take over and they catch the public's imagination and naturally, the donation flow starts to diminish."

He said it would be around that time that victims began to rebuild.

During the first few months, homes needed to be inspected, insurance claims finalised and asbestos cleared from the land, he said.

"But, of course, by then the focus of the public has gone elsewhere," Mr Dunn said.
